Dophin H80/H100 vs SOBO WP-880/WP-1880: Filter or Pump for a Small Tank?

Dophin H80 and H100 are often compared with inexpensive SOBO pumps because all four products move aquarium water and are easy to find in Malaysia.

That comparison can be misleading.

Dophin H80 and H100 are hang-on-back filters with a media compartment. SOBO WP-880 and WP-1880 are submersible powerheads. A bare SOBO powerhead can circulate water and add aeration through a venturi attachment, but it does not automatically provide the same mechanical and biological media space as a complete HOB filter.

Quick verdict: for most beginner small tanks that need one primary filter, Dophin H80 or H100 is the more complete starting point. Choose a SOBO WP-880 or WP-1880 when you deliberately need a pump to drive a top filter, increase circulation, add aeration or move water through another filtration component. Do not choose the SOBO model simply because its rated flow is higher or its asking price is lower.

This is a practical Malaysia buying comparison based on visible package specifications, manufacturer information, July 2026 marketplace asking-price samples and selected buyer comments. It is not a laboratory test of real flow, noise or long-term durability.

If you are still deciding between sponge, HOB and internal filtration, start with our small-tank aquarium filter guide for Malaysia.

Price and evidence note: Asking prices, stock, vouchers, sold counts and ratings can change. The marketplace listings observed contained multiple models, and some even mixed different brands or accessories in one variation menu. Their total sold and rating figures cannot be assigned to one specific model.

Quick answer: which one should you choose?

Your actual need	Better starting point	Why
One compact primary filter for a beginner tank	Dophin H80 or H100	The filter already includes a water path and media compartment
Betta, shrimp or slow-flow livestock	Usually Dophin H80, or a sponge filter	Lower rated flow is easier to manage, although intake and waterfall flow may still need softening
Small community tank with moderate flow	Dophin H100	More circulation than H80 while retaining an accessible HOB media compartment
Pump for a separate top-filter box	SOBO WP-880 or WP-1880	These powerheads are designed to move water through attached plumbing or an upper filter system
Strong circulation or aeration in a suitable setup	SOBO WP-880	High rated output for a compact pump, but too strong for many small low-flow tanks
Higher lift or stronger top-filter drive	SOBO WP-1880	Higher rated flow and head than WP-880, with greater power use and stronger-current risk
Very small nano tank	None of these by default	A properly sized sponge filter may be easier to control

The correct question is not “Which model is strongest?” It is:

Do you need a complete filter, or do you need a pump for another filtration system?

Side-by-side specifications

The Dophin figures below follow the Malaysia 220–240V / 50Hz package sample collected in July 2026. The SOBO figures follow the product specification image supplied during the same research.

Model	Equipment type	Seller/package-rated flow	Power	Maximum head	Media included in the device	July 2026 asking-price samples
Dophin H80	HOB filter	185 L/h	2.5W	Not stated	Cartridge and biological-media housing	RM21.90–RM22.40
Dophin H100	HOB filter	350 L/h	3.0W	Not stated	Cartridge and biological-media housing	RM27.20–RM27.70
SOBO WP-880	Submersible powerhead	800 L/h	15W	1.0m	No comparable HOB media chamber in the bare pump	RM7.20–RM12.39
SOBO WP-1880	Submersible powerhead	1,200 L/h	20W	1.2m	No comparable HOB media chamber in the bare pump	RM18.29–RM20.33

Why Dophin specifications may look slightly different elsewhere

The Malaysia package sample showed 185 L/h and 2.5W for H80, plus 350 L/h and 3.0W for H100. A current manufacturer page lists H80 at 190 L/h and 2.7W, and H100 at 350 L/h and 3.4W for a 230V / 50Hz configuration.

That small difference is exactly why buyers should check the label on the current unit rather than treating one seller table as universal. This guide uses the Malaysia package sample for the main comparison and records the manufacturer variation instead of hiding it.

Rated flow is not real installed flow

The printed L/h figure is a maximum or seller-rated value under its test conditions. Real output can be lower because of:

• lift height
• tubing length and bends
• clogged sponge or cartridge
• extra filter media
• a dirty impeller
• restricted intake
• water level and return height
• flow-control position, where present

A pump with a higher number is not automatically a better filter. Flow only moves water. Filtration also depends on where the water travels and how much suitable mechanical and biological media it passes through.

---

Nominal turnover shows why SOBO can feel excessive

The table below divides rated flow by example net water volume. It is only a warning illustration before plumbing, media and head losses—not a measured performance result.

Model	At 20L	At 40L	At 60L
Dophin H80, 185 L/h	9.3×/hour	4.6×/hour	3.1×/hour
Dophin H100, 350 L/h	17.5×/hour	8.8×/hour	5.8×/hour
SOBO WP-880, 800 L/h	40×/hour	20×/hour	13.3×/hour
SOBO WP-1880, 1,200 L/h	60×/hour	30×/hour	20×/hour

These numbers do not prove that every WP-880 is unusable below 60L. Outlet direction, lift and attached equipment can reduce the current. They do show why a bare WP-880 or WP-1880 should not be treated as a gentle plug-and-play choice for a small betta or shrimp tank.

Dophin H80: the lower-flow complete filter

Best for: Lightly stocked small tanks where the keeper wants an accessible HOB media compartment and lower flow than H100
Not ideal for: Tanks with no rear clearance, very low water levels, fry without intake protection, or fish that struggle with the waterfall return

The H80 hangs on the rim, pulls water through an intake and returns it over the edge. Its main advantage over the bare SOBO pumps is not raw power. It is the complete filtration path.

The package describes mechanical and biological filtration, a carbon cartridge and housing for beneficial bacteria. In practice, the useful part is the ability to retain mechanical media and established biological media in an accessible chamber.

Do not assume that the carbon cartridge must be replaced every two months forever. Activated carbon is useful for specific chemical-removal purposes, but routine aquarium stability depends more on keeping suitable biological media mature and cleaning clogged mechanical media without destroying the bacterial colony.

H80 buyer-feedback signal

The visible H80 comments collected during research mainly covered delivery and condition. One user reported that the filter operated smoothly without noticeable noise. That is a useful signal, but one comment cannot prove that every unit is silent or durable.

H80 practical judgment

H80 is the safer of these four products when the goal is a gentle primary filter, but it is not automatically safe for every betta, shrimp or fry tank. Consider:

• adding a pre-filter sponge to the intake
• keeping the water level close to the return to reduce waterfall force
• baffling the outlet if long-finned fish are pushed around
• confirming that the filter remains primed after maintenance or a power interruption

For a betta-specific decision, read whether betta fish need a filter and how gentle the flow should be.

Dophin H100: more flow without changing filter type

Best for: Small community tanks that need more circulation than H80 and still benefit from an external media chamber
Not ideal for: Tiny low-flow tanks chosen only from seller length claims

H100 has almost twice the package-rated output of H80: 350 L/h instead of 185 L/h. That difference is large enough to matter in a small aquarium.

Choose H100 because the tank and livestock can use the extra circulation—not because it costs only a few ringgit more.

Seller tank-length claims should not be treated as a general recommendation

The observed seller material associated H80 with roughly 15–25cm tanks and H100 with roughly 25–35cm tanks. Those figures are too simple to use as universal guidance.

Two tanks with the same length can have very different:

• water volume
• height and width
• fish load
• feeding level
• plant mass
• substrate displacement
• tolerance for current

A 30cm betta tank and a 30cm guppy grow-out tank do not need the same flow pattern.

H100 buyer-feedback signal

One H100 user described the pump as so quiet that they initially wondered whether it was running. Another reported normal operation. These comments support a limited “quiet for some buyers” note, not a guaranteed noise rating.

H100 practical judgment

H100 is the more balanced choice when H80 feels underpowered for a modest community setup. It still needs realistic maintenance and media planning. A higher flow rate cannot compensate for overstocking, overfeeding or an uncycled tank.

Before adding fish to a new filter, follow the beginner aquarium cycling guide.

SOBO WP-880: cheap, compact and much stronger than it looks

Best for: Driving a compatible top filter, adding circulation or using a venturi in a setup designed for stronger water movement
Not ideal for: A beginner who thinks the bare pump is a complete gentle filter for a small tank

WP-880 is rated at 800 L/h, 15W and a 1.0m maximum head. Its compact body and low asking price can make it look like the obvious budget winner.

It is not a direct H80 replacement.

The bare WP-880 has no HOB-style media basket. If it is used only as a powerhead, it moves and aerates water but does not provide the same controllable media path as the Dophin filter. To function as meaningful primary filtration, it needs an appropriate attached sponge, top-filter box or other media system.

Do not confuse WP-880 with WP-880F. The F version refers to a complete top-filter configuration sold with additional filter hardware. This comparison is about the bare WP-880 powerhead shown in the approved image and research listings.

WP-880 buyer feedback shows both sides

One repeat buyer said the pump had been reliable for a long period and purchased another as a standby. That is useful long-term anecdotal evidence from one user.

Another buyer reported that WP-880 created a storm-like current in a tank under two feet and felt it was too powerful. That review is especially relevant because it describes an actual mismatch between pump output and tank size.

Both comments can be true. The experience changes with outlet direction, aeration attachment, plumbing resistance, tank dimensions and fish type.

WP-880 practical judgment

WP-880 can be good value when you already know where its 800 L/h output will go. It is poor value if you later need to buy extra parts, improvise a baffle and still cannot create suitable flow for the fish.

For a low-flow tank, a sponge filter may be a simpler alternative. Our quiet aquarium air-pump guide explains what the separate air-pump setup involves.

SOBO WP-1880: a stronger system pump, not a nano upgrade

Best for: Driving a compatible top filter or circulation system that needs more flow and lift than WP-880
Not ideal for: Small low-flow tanks, buyers choosing only by cheap asking price, or any aquarium where the pump housing arrives damaged

WP-1880 is rated at 1,200 L/h, 20W and a 1.2m maximum head. It is a meaningful step above WP-880, not a small upgrade comparable to moving from H80 to H100.

The extra head and flow make more sense when water must travel upward to a top-filter box or through plumbing. Used bare in a compact tank, it can create excessive directional current and occupy swimming space inside the aquarium.

WP-1880 buyer feedback needs context

One buyer said WP-1880 felt appropriate in a relatively small aquarium after an earlier pump had been too strong. The review did not state the tank dimensions, outlet direction, lift height or attached filter system, so it cannot become a universal small-tank recommendation.

The same buyer reported that the unit arrived cracked but continued to run. Do not follow that example. A cracked housing, damaged cable or compromised submerged electrical device should be returned or replaced, not tested for weeks in an aquarium.

WP-1880 practical judgment

Choose WP-1880 only after planning:

• the filter box or media it will drive
• the vertical lift
• hose diameter and bends
• the intended return position
• how the fish will escape the strongest current
• whether 20W of continuous power is justified

If none of those details has been planned, H100 is usually the clearer beginner purchase for primary filtration.

Price comparison: the cheapest pump is not the cheapest filter

The July 2026 asking-price samples make SOBO look much cheaper:

Model	Observed asking-price range
Dophin H80	RM21.90–RM22.40
Dophin H100	RM27.20–RM27.70
SOBO WP-880	RM7.20–RM12.39
SOBO WP-1880	RM18.29–RM20.33

But the products do not include the same function.

A fair cost comparison may need to include:

• separate top-filter box
• sponge or mechanical media
• biological media
• tubing and fittings
• flow diffuser or spray bar
• pre-filter sponge
• replacement cartridge or reusable media
• electricity use over time

WP-880 can cost less at checkout and still cost more to turn into a usable filter system. Dophin can cost more upfront but already provides a media compartment.

Prices are snapshots, not fixed market averages. Vouchers and multi-variation listings can also make the displayed headline price belong to a different accessory or model.

---

Do not assign listing sales to one model

The Dophin listings observed showed roughly:

• 3k+ sold with 1.2k ratings on one multi-variation listing
• 2k+ sold with 1.1k ratings on another multi-variation listing

Those listings included several Dophin sizes, and one also displayed SOBO variations. They do not prove that H80 or H100 alone achieved those totals.

The SOBO listings showed 20k+ sold with approximately 4k or 5.1k ratings, but the variation menus covered WP-880, WP-1880, larger WP models and, in one case, unrelated Xinxiu models or air tubing.

The totals show that the broader product families have marketplace activity. They are not model-level sales evidence.

Which one is better for betta, shrimp, fry and community fish?

Betta fish

Start with H80 only if the outlet and intake can be made gentle. H100 may be excessive in a very small betta setup. WP-880 and WP-1880 are not sensible bare-pump defaults.

Shrimp and fry

None of the four is automatically shrimp-safe. H80/H100 need a pre-filter sponge. SOBO powerheads need suitable intake protection and should not create a strong open current. A sponge filter is often simpler.

Guppy, molly and small community tanks

H100 can suit a modest community tank when the fish tolerate the current and the tank is not overstocked. H80 may suit a lighter setup. SOBO can work as part of a planned top-filter system, not merely as a loose pump pointed across the tank.

Goldfish, Oscar or high-bioload fish

Do not use the low asking price of these devices to justify an undersized tank or filtration system. High-bioload and large-growing fish need realistic water volume, media capacity and maintenance—not only a high L/h number.

If water becomes dirty quickly, investigate stocking and feeding before buying a stronger pump. Read why aquarium water gets dirty so fast.

Maintenance differences

Dophin H80/H100

• Fill or prime the filter before first use as instructed.
• Rinse clogged mechanical media in removed aquarium water where practical.
• Preserve established biological media instead of replacing everything together.
• Clean the intake and impeller when flow drops.
• Keep the water level high enough to reduce waterfall noise and restart problems.
• Use activated carbon for a clear purpose rather than as an automatic permanent consumable.

SOBO WP-880/WP-1880

• Keep a submersible pump properly submerged during operation.
• Never run it dry.
• Unplug it before putting hands into the tank or cleaning the impeller.
• Inspect the housing, cable and plug before use.
• Clean the intake and impeller when output falls.
• Check hoses and top-filter plumbing for blockage, kinks and leaks.
• Make a drip loop and keep electrical connections away from splashes.

A buyer comment that a cracked pump still worked is not evidence that it was safe.

Final recommendation

Choose Dophin H80 when:

• you need one simple primary filter
• the tank is lightly stocked
• lower flow matters more than maximum circulation
• you want filter media outside the tank
• you can protect the intake and soften the return if needed

Choose Dophin H100 when:

• H80 is too weak for the intended small community setup
• the fish tolerate moderate flow
• you still want an accessible HOB media chamber
• the tank has enough rear clearance

Choose SOBO WP-880 when:

• you specifically need an 800 L/h submersible powerhead
• it will drive a compatible top filter or planned media system
• the livestock and layout can handle the resulting current
• you understand that the bare pump is not equivalent to an HOB filter

Choose SOBO WP-1880 when:

• the system genuinely needs 1,200 L/h rated output and more lift
• the pump will drive an appropriate filter or circulation layout
• you have planned the return flow and safety precautions
• the tank is not a small low-flow setup

For most beginner small tanks, the safer default is Dophin H80 or H100, selected by real tank volume, livestock and flow tolerance.

SOBO wins on raw rated output and low asking price. Dophin wins when the buyer needs a more complete standalone filter rather than a pump that still needs a filtration plan.

FAQ

Is SOBO WP-880 a complete aquarium filter?

Not in the same sense as Dophin H80. WP-880 is a submersible powerhead. It can drive a top filter, circulate water and add aeration, but the bare pump does not provide a comparable external media chamber. Meaningful filtration depends on what media or filter system is attached.

Can I use SOBO WP-880 in a tank under two feet?

It may be physically possible, but one buyer specifically found the current excessive in a tank under two feet. The result depends on water volume, outlet direction, lift, attached equipment and fish type. It is not a gentle default for a small tank.

Is Dophin H80 suitable for a betta tank?

It can be suitable when the tank is large enough and the intake and return are softened. Watch the fish rather than trusting only the L/h number. If the betta is constantly pushed, hiding or struggling to rest, reduce or redirect the flow.

Is H100 better than H80 because it has more flow?

Only when the tank needs the extra circulation. H100 can be more suitable for a modest community tank, but stronger flow can be worse for a tiny tank, long-finned fish, shrimp or fry.

Why is SOBO cheaper despite having much higher flow?

Because rated flow does not describe the whole filtration system. The SOBO models are bare powerheads, while Dophin H80/H100 include a HOB body and media compartment. Extra filter hardware and media can change the real total cost.

Can WP-1880 replace H100?

Not as a direct one-for-one replacement. WP-1880 moves much more water and is better viewed as a pump for a planned top-filter or circulation system. H100 is a complete small HOB filter.

Do I need to replace the Dophin carbon cartridge every two months?

That is a seller or package recommendation, not a universal aquarium rule. Carbon has specific uses, but stable biological media and properly maintained mechanical media are more important for routine filtration. Do not replace all mature media at once.

Which model is quietest?

A few Dophin buyers described H80 or H100 as quiet, and one SOBO buyer described long-term reliable operation. There is not enough controlled evidence to rank noise. Water level, mounting, trapped air, impeller condition and vibration against the glass can change what you hear.
