## Customer Reviews

### ⭐⭐⭐⭐⭐ Solved my cloudy water problem
*by R***T on May 5, 2020*

I have a ten gallon tank equipped with a Seachem Tidal 35 power filter, a lot of filtration for a small tank. Nevertheless, the Seachem wasn't picking up small particles in the water which were abundant because I have a planted tank with heavy stocking. This little sponge filter made my tank crystal clear overnight. I loaded the media hopper with some Seachem Denitrate to keep my nitrates low and they've stayed at zero. Very pleased with this product.

### ⭐⭐⭐⭐ Design could be slightly better for locking media portion
*by S***A on September 4, 2020*

Place where you put media, there is no locking mechanism so when taking out all media could drop in your tank so need to be careful.The other problem which I had with my airline tube is that my existing air line tube based on their instructions on back, it should be able to insert my tubing thru point no 2 in their diagram and insert to point no 9. I was not able to put my tubing thru point no 2 but I did directly attached to point 9 which is kind of slightly loose. I am not sure whether airline tube comes in different diameter or they are standard.

### ⭐⭐⭐⭐⭐ Sponge filter
*by J***N on January 16, 2021*

I bought this for a 5 gal betta tank and it seems to be doing a good job of keeping the tank clean.
