What is the minimum amount of water (20 Gallon long tank) in inches needed for this filter to work properly? it is for a turtle
Answer by ChewyJan 12, 2018
To use this product you will need approximately 6-7 inches of water.

Would you recommend a small 5-10 or a 10-20 for a 10 gallon tank?
Answer by ChewyAug 07, 2019
To determine which filter is best for a 10 gallon tank, it's best to consider what type of fish is in the aquarium. For example, if you may have a betta fish then the smaller filter may be more appropriate however, if you may have other species or multiple fish in the tank, then the larger 10-20 may be better.

Can i use 2 filters for a 55 gal tank?
Answer by ChewyJan 23, 2018
You can certainly use 2 filters. Just ensure it's paired close enough to 55 gallons.

stupid question. does it also put some oxygen in the water.
Answer by ChewyJul 21, 2019
Filters move water from the top to the bottom of the tank, thus distributing oxygen throughout the aquarium.

Great Filter

I have three cats, and was looking for a filter. That could not be in the way. Of allowing for a tank cover. For the top. When I had goldfish as pets. At age 11. In a 20 gallon aquarium. I had one of those whisper-quiet filters that hung on the side of the tank. It was a great filter. This one is whisper quiet as well. It seems to be reliable in getting the tank clean. It sucks up whatever leftover flakes my two goldfish don’t eat. My cats have said hello to the fish. Sitting by the tank. But, never have really bothered them. I’m glad to have a filter. That can allow for a tank cover. It also is cleaning up the beneficial bacteria. It’s a slow process. But, I think it’s getting the job done on that too. With how powerful it is. Getting the leftover flakes sucked up.

Complete Trash

This thing broke within a month of using it. I would never recommend anyone to buy this trash. When I first received it, the box was broken meaning someone opened it before, then I noticed something is the back of the filter was broken but I ignored it since it wasn't important. Please do not waste your money on this garbage.

Stopped working

I had it in my freshly cleaned tank for less than a week and it stopped working. There is a 2 year warranty but you pay for shipping so it wouldn't be worth the money. :(

Works better than expected

I am using this in a tall 5G and must say that it works better than I expected it to (compared to the usual teeny filters I use for small tanks). That being said, it is quite large and clunky. It takes up a lot of space in the aquarium. Not great if you have an aesthetic you're going for. On the good side, it creates great water movement, has an adjustable height, and uses high quality filtration, which I feel is uncommon in filters for small tanks.

Came back to write review

I came back 2 years later to say this filter is still old reliable. Followed the care instructions and it's worked wonders for my 20 gallon tall. Would recommend!

Too noisy

The item is too noisy. It makes a lot of noise in the middle of the night.

Useful but suddenly stopped working

This is great for keeping my turtle tank clean unfortunately it just stopped working on me one day. I've never been able to figure out why or get it working again since so I just have to purchase another one before the tank starts to reek. : (
