Review on Powkoo Aquarium Filters Sponge Containers by Claudia Muhammadi

I had a big mess in this aquarium. We had a flood and it messed up the water in my well, I didn't think it would do anything to the water in my aquarium. boy was i wrong! You couldn't look into the aquarium and my tests were crazy. I bought this filter to use with another sponge filter and it got my tank sparkling clean in just a few days. I took out the bio balls and added ammonia chips and am very happy with the results!
