Review on Aqua Flo Aquarium Filter Media Thick by Claudia Garza

I have 2 turtles in separate tanks with separate canister filters. One tank had 1 small fish with a softshell turtle and the other tank had 2 adult goldfish with my red-eared slider. I read all the good reviews about this medium and decided to give it a try as a cheaper replacement for mechanical filters. I've used both the Penn Plax brand cascade filters and their generic version in my canisters with no problems. I bought them and cut them to fit. I cleaned and restarted everything as usual. I did notice that the carrier is very thin but with all the great reviews I thought it would be ok. The next morning I noticed cloudiness in both tanks. I thought it might just be some kind of color transfer and it will go away in a few days. After about 5 days it only got worse, not better. I got scared and wanted to change it after work in the evening. I was late and my little fish had already died and my adult fish barely swam. Before I could change anything, one of the adults died too. I am so frustrated and will never use these cut to size filter media again!
