Review on 🐠 DEPEPE 10pcs Zipper Aquarium Filter Media Bags for Activated Carbon, Biospheres, Ceramic Rings, and More by Julie Valenzuela

Slightly larger than expected but after a few days they worked, blacks released dye into my tank and my filter turned black mind you I just cleaned the tank. So I changed the water and filtered again the next day, this time the same thing happened, it killed my angelfish. Everything changed again, new black bags, everything turned black, the fish lost their place. I don't use the other bags, please be careful when you buy them, they're the only thing we did differently when cleaning the tank.
