Reviews sunsun | Water Circulation Fish Tank Filter System – Real User Experiences

It's super quiet and doesn't take up much space, perfect for small fish tanks. The noise reduction is great, and the quality is top-notch. It effectively removes oil film, and overall, I'm really impressed. The customer service sent over an easy installation video, and they were very patient. I'm pleased with the service and will keep an eye on it to see if there are any leaks later. The craftsmanship is quite detailed, and the filtration works well. I recommend it for anyone with larger fish to use in a cycling container with the filter.

It's a bit pricier than other options, but I chose this one because it looks great and the color matches perfectly. The only minor issue is that the spray pipe is made of two parts put together, but it doesn't affect the use.

Where's the promised full box of filter material? Why did I get the old model when there's a new one with a clear window? The filter sponge isn't even as wide as the box.

The installation was easy, and it looks nice with the right color. There are no leaks, and overall it's functioning pretty well.

Easy to install with no leaks so far. The materials have a slight smell. The appearance and color are nice, and there's no damage. The filtering isn't great, can't remove fish waste and debris. It's noisy during use, especially the water flow at night when it's quiet.

As a newbie to fishkeeping, I set up the fish tank and added the fish a few days ago. By the fourth day, the water started to smell and turned yellow. I quickly searched for advice, and many people recommended using a filter box. I found this one, and the pump is strong! After running it for just half an hour, the water became clear again and the smell disappeared. If you have space for a filter box, definitely get one!

It works well, though a bit more attention to the fit and finish would be great. The assembly is straightforward, and with a small adjustment, the connection stays secure.

The connection was super easy, and the customer service was awesome. The pump is really powerful; I have a tank that's 60*37*21 and got the one the customer service suggested. The cleaning power is impressive; it cleaned my volcanic stones in just 20 minutes. If you need one, go for this store without hesitation.

Awesome! The quality is fantastic! Highly recommended and trustworthy! Friends who like it can go for it.

I checked the reviews and noticed some issues with the lid not sealing properly, so I asked the warehouse to check before shipping. However, the lid still wasn't secure, and the first and second layers of the casing were a bit warped with some white wear. The fish were in need of oxygen, so I told customer service I could use it for a few days and then return the original for a replacement. They were very responsive and offered me compensation. Honestly, it doesn’t compare to the quality of another brand, but I'm making it work even though I had to adjust the setup since my stand isn't high enough. It took a bit longer, but I'm managing.

Installation difficulty: easy. Noise level: a bit noisy but acceptable. Product quality: quite good. Filtration effect: very nice.

The standard quality is great, and the nitrifying bacteria clear the water super fast. The customer service, 'c1 after-sales,' is very responsible. I've always trusted the after-sales support from Sen Sen.

The filter works great, keeps the tank clean. No need to look up different filters online, just go for the storage box.

The first layer has some defects and the lid needs fixing, but it still works. The second layer's drain hole requires some repair, and there are scratches and oil stains. The last layer also has minor issues that need adjustments. It's functional despite these issues. Might be unlucky, but it’s usable.

The pump is powerful, and I've already ordered a smaller one. It was easy to install, and even though the tank hasn't arrived yet, the water in the bucket became clear in just one day. Great product!

Super impressed! No more water noise, the box is really well-made, super easy to install, I'm really happy with it.

👌Ease of Use:yes\n 💧Filtration Quality:ok\n 🔧Maintenance:ok\n Easy to install, Compact filter box design.\n

My tank is 40 liters, and after running the filter for a day, it's working really well. The 6-watt SunSun pump is more than enough, and it's pretty quiet too.

The quality is great, it comes with all the necessary accessories, and it's easy to use.

Easy to install, and the color looks great!

It looks great and the seller has a good attitude. The installation was simple following the video, it's quiet, and after a week of use, the water quality is clear and the filtration is effective.

The design looks great, and the service from the seller is excellent. I followed the video to install it, and it was pretty straightforward. It has low noise, and after using it for a week, it's still working well. The water quality is clear, and the filtration works great.

The quality is great, the accessories are complete, and it's easy to operate.

Absolutely beautiful! The filter works brilliantly! They even included extra filter material! Such a great seller! Wishing the owner great business success!

The quality is good, the color is nice, easy to set up, recommend buying

The seller is really attentive and answers every installation question with patience, explaining everything clearly. After installation, there was an issue with water flow, but they quickly found the cause and fixed it. During use, the water pump runs smoothly without noise, and the whole filtration system works well with noticeable results.

The craftsmanship and materials are great, and it comes with all the necessary parts!

The box is slightly bent with a few minor scratches and some rough edges.

Swapped the curved pipe and the tee, and it perfectly solved the issue of stagnant water smelling in the bottom storage box.

The water flow is quite low and there isn't much suction! The fish didn't make it, and there's fish waste everywhere! The after-sales service is a bit messy!

Super easy and quick to install, saves time, ready to try it out!

I’ve been using the product for a while now, and the craftsmanship is excellent, really exceeded my expectations. It's great!

It's pretty good, the items are complete, attractive, practical, and user-friendly for beginners.

The filter works great, just like a fish in water. It's easy and carefree; otherwise, the fish wouldn't be able to get rid of bacteria and waste. There's definitely an art to fishkeeping.

Product quality: The material is really thick and well-made. Filtration effect: The filtering system works great! No noise: It's silent and easy to install. Awesome!

The fish tank has two removable covers, and with the light fixture kept, it fits perfectly.

The aquarium's two covers were removed, keeping the light holder, and it fits perfectly.

The filter box is quite simple, and the filter cotton is a bit narrow and seems short. The pipe connectors feel loose, so I decided to use it in a traditional setup just to be safe. I think the filtering capability is okay, as the water stays clear.

The water flow is a bit loud, but the filtration is excellent. More reviews to follow.

This is super handy! The first layer of the filter has an overflow prevention, so no worries about clogs and water leaks anymore. I picked a box that's a bit small for my 80×40×45 fish tank; I should have gone for the medium one, 40×30. The box size should match the tank's width. It's still usable now, but I'll switch to a medium one later and pair the small box with a 60×30 tank.

This product works really well! The first filter cotton compartment even has an anti-overflow outlet, so I don't have to worry about water leaking if the cotton gets clogged. I did choose a smaller size for my tank, it's 80×40×45, and I should've gone for a medium size like 40×30 instead. The box size should match the width of the aquarium! It still works for now, but I plan to upgrade to the medium size later, and maybe grab a small one for a 60×30 tank!

Installation difficulty: easy. Whether there is noise: To get silent water, you have to slowly fine-tune the switch to the minimum. But this switch is too hard and tight. It's easy to turn it on full blast during the day, but at night, it takes 10-20 minutes to slowly adjust the switch to the minimum when sleeping. If you twist it too hard, it overflows; if you don't twist it hard enough, the water pipe gurgles with air. Filtering effect: The filter material in the package should be fine for a year.

Not bad, really useful, the water quality has improved, and the fish are swimming happily. Filtration effect: great. Product quality: decent. Noise level: very low. Installation difficulty: easy.

Very happy with this purchase! The filtration is great, and the water is clean now.

I’m really happy with this purchase! The filter works great and the water is so clean now.

Absolutely fantastic, no more water noise now. The quality of the box is great, very easy to install, very satisfied.

Installation is easy! No noise at all. The product quality is average. The filtering effect could be better! After using it for a week and changing the filter cotton once, I noticed the water got a bit cloudy. I started by adding half tap water that sat for about four days and half pure water that also sat for four days. Initially, the bottom suction pump had some issues with not picking up fish waste, and during the week, I had to manually clean it almost every day. The pump itself seems to have no power issues, but it just didn’t get the fish waste, and the water became a bit cloudy. Overall, it didn’t quite meet my expectations, but it's a decent setup for simple use.

I bought a storage container and set it up with water to keep goldfish in this big plastic basin I wasn't using. I can't let the warm autumn sun go to waste.
