Upettools Aquarium Biochemical Double Sponge Filter up to 55 Gallon Green

Product Review (submitted on April 25, 2022):

I'm new to sponge filters, so still observing and learning. I like to try out different types of filtration. But leaning more towards sponge filtration.

I purchased this originally for a small 5 gallon tank, but ended up adding to my overstocked 20L community Guppy tank. The sponge filter I originally used support the tank (different brand) I found could not handle the load. So, I added this filter to the tank and it's made a world of difference. On a tank with with the proper amount of fish, I believe this filter could support the tank on it's own.

I like the fact that this filter comes with chambers to allow for other media. Be advised, they are small chambers, but I have added floss in the past and it worked great. I plan on purchasing a second one for a 5 gallon Marineland tank that had an awful built in overflow filter that I just recently removed.

I also also use two different size airline tubing in my tanks. I found the 3/16 inch works well with this filter. I'm using a Whisper (100) with two 4-way air flow control lever valves connected to it. This is more than enough air flow to support two sponge filters in the 20L, as well as several small 5 gallon tanks.
