Reviews sunsun | 3-in-1 Small Wall-mounted Filter for Fish Tank and Aquarium – Real User Experiences

I have to give a big thumbs up to both the customer service and the product! The support was super attentive throughout, and the attitude was fantastic. The product is well-made, easy to install, and runs really smoothly. Overall, it was an awesome shopping experience!

The wall-mounted filter is a lifesaver for small tanks! Its 3-in-1 design combines filtering, oxygenation, and circulation, hanging on the tank wall to save space. Perfect for fish tanks or turtle tanks under 30cm. The waterfall-like flow looks nice and boosts oxygen levels in the water. It runs quietly with only a gentle water sound, not disturbing at all. It has an adjustable flow valve to control water strength as needed. Easy to install with all parts included, even girls can handle it easily. The filter box size is just right and easy to clean. The only minor downside is the filter sponge needs regular replacing, but overall it's great value for money and perfect for beginners or those who like a simple fish-keeping experience!

The pump's power is quite strong, and the water flows really fast. It's very handy to use, and the best part is the cord is long enough. I've used it for a week and it feels pretty good.

It's compact and pretty practical, super convenient for my aquarium, makes hardly any noise, really good.

The kids set it up by themselves, so it must be easy. After adding the filter, the water quality improved a lot. Before, the water would get cloudy in less than a day, but now it stays clear for four days.

Really nice, specially recommended by the customer service, great value.

It's compact and really useful, super convenient for my aquarium, makes hardly any noise, pretty great!

The customer service is really great, they answer every question carefully, and I'm a regular customer. I'll definitely be coming back next time.

The build quality is decent, nothing super fancy, just average. Installation is a breeze; just watch a quick video for a minute or two, and you're good to go. Customer service is great, very responsive and accurate with answers. The noise level is low; you can hardly hear it from three steps away.

I had one at home that broke, so I bought another one just like it. The craftsmanship is great and it's really practical.

The fish my son caught from the river are in the tank in the room, it's super quiet, really nice 👍 worth buying

Installation was easy. It makes some noise when you first start it, but once it's running, it's really quiet. The quality is good; you get what you pay for. The filtering works really well, and overall, I'm quite satisfied with it.

It's quiet and the water flow is adjustable. I added some cashmere wool and quartz balls, and I hope that makes a difference. I had to shave a bit off the top cover to get it to fit.

It's really quiet and easy to install, even if you don't know how to at first, the customer service is very helpful.

The filter is great, especially the waterfall feature, awesome.

The product works perfectly fine. It's more than enough for my 40-gallon tank. Advantages: 1. It's genuinely quiet. If you're very particular about any slight vibration, just put a piece of cloth behind the wall mount. 2. Installation is super easy. 3. I use the filter a bit differently from the instructions to allow more water to pass through the filter media; you can DIY it. Drawbacks: Some of the slots aren't very tight; using a cloth for padding works better.

It's easy to set up, and the water flow starts quickly after installation. I always buy oxygen pumps from this brand, and they are great.

There's no noticeable vibration, just a gentle flow sound. After a day, the water quality has definitely improved a lot, very nice.

Super quiet and the water flow is strong.

The carbon plate had some issues with leaking, and after discussing with customer service, we tried various solutions. The best outcome was finding that it only leaked when set to a higher level, which was manageable. The staff was helpful in suggesting adjustments. I’ve also tried other brands for filtration, and while this one has its quirks, the setup works fine if handled correctly. It’s a good idea to keep things simple with just the filter cotton and adjust accordingly to avoid any leaks.

Pretty good, hardly any noise, easy to clean, decent filtration, just wish the outlet was a bit higher so I could use it without a mat.

It's pretty good, almost no noise, easy to clean, filtering works well, but the water outlet is a bit low, so you need to elevate the filter to use it.

Item looks good, Durable SUNSUN brand quality, Compact for small aquariums, affordable price

Assembly is easy, the water flows quickly once installed, and I've always bought their aeration pumps. They're great!

This is a great product! After setting it up in the tank, it immediately started working. There was a lot of fish waste in the tank before, and the previous filter didn't work at all. With this filter, all the waste was gone in just 1-2 minutes! I was really impressed by that. Plus, the water flow is almost silent, which is nice. After leaving it on overnight, the water was noticeably clearer. It used to be quite murky. Overall, I'm satisfied!

This filter does a decent job and is effective. However, the space for the filter media is a bit limited, which might be a challenge for beginners in fishkeeping.

Installation is easy. It's very quiet, so you can use it in a room. The product quality is a decent filter. The filtering effect is okay, just needs a slight adjustment.

This thing is pretty small; I don't think the filter material fits well. The customer service suggested breaking it up to fit it inside.

Be really careful with this. This device can't pick up any fish waste in my 60-liter tank. I thought it was the fish's fault and kept adjusting the feeding, but I realized it just can't pick up any fish waste. I ended up having to clean it by hand.

The craftsmanship is great, and I suggest adding some quartz balls inside the filter box. I added quartz balls and cotton cloth myself.

It's quite quiet, and the filtration seems to be working well so far. The 302 comes with two filter plates, but I've only used one and didn't place it in the designated slot to make more room for quartz balls, maximizing the space. The filter chamber mainly relies on cashmere filter cotton for physical filtration, and I only have the quartz balls and one original filter plate in there. Once I get more fish, I feel like I could remove the filter plate entirely and use that space for more filter media. I also put a digital thermometer I made on top, and it looks good too.

I got one of these and found it not very useful. I switched to a different one that's way better. I was looking for something reliable as a beginner and had a pretty decent experience with customer service.

It's really great, completely silent, no noise at all.

The water pump is great, and the store's service attitude is good too. It's easy to install, really nice!

The product is great, and the customer service was very helpful, sending a new one right away after a minor issue. It took a couple of days, but I appreciate their support!

I used a 40 tank and found this filter doesn't quite hold up for a full day. The suction isn't strong, and it tends to have some hiccups after restarting, like the water not flowing or the filter media getting clogged. The customer support was a bit slow to respond. I'll consider other brands in the future.

Had a leak, customer service had me try a bunch of things only to find out it was a manufacturing flaw or maybe a returned product that someone else used. Ended up fixing it myself with some sealant. Nowadays, even big brands don't really care about after-sales service or product quality. They just act like everything is perfect and whether you're happy or not doesn't matter to them. Thanks and goodbye.

It broke after a month of use, and the support didn't really help—just had to toss it. The quality is definitely something to think about. Support only covers the first month, which is a bit silly.

This is a really quiet water filter that's super easy to install and you can adjust the water flow, which is nice.

Connecting the pipes takes a lot of effort, but the hollow design at the bottom makes it easy to snap, showing a clear design flaw that affects the oil film filtration.

The seller's service was really great, and the quality of the product is pretty good too. I'm really happy with it, thanks!

Really great! The customer service is super responsive! They're really knowledgeable and answer all questions. The accessories are complete and installation is easy. I have to say, after changing this out, the little fish in the tank look so much better!

This little gadget is pretty great! It's really convenient and perfect for small tanks. I'm still figuring it out a bit, but during normal use, it's almost silent, just the sound of the water.

Really great! Customer service is very responsive! They're super professional and answer all questions. The installation is easy and the accessories are complete. I have to say, after switching this out, the little fish in the tank look so much better!

I have to give a big thumbs up to both the customer service and the product! The support was so thoughtful throughout, and their attitude was fantastic. The product is well-crafted, easy to install, and runs smoothly. It was an awesome shopping experience!

I couldn't figure out how to set it up at first, but after asking customer service, I had it installed in just two minutes!

Very nice, highly recommended by customer service, really worth it.

This is my first time using this, and it's great for entertaining the kids while keeping a few small mixed fish. It's not really suitable for long-term fish keeping, though.

The customer service responds quickly, the installation is very easy, the motor is quiet, and the filtration effect seems promising. The fish need a few days to adjust, and I hope they grow well.
