CNZ® Aquarium Filter Media Kits (Double Pack) - Activated Carbon, bio Ball, Ceramic Ring

have a 1500 gal koi pond which had tea colored water. I purchased two 5 pound activated carbon in media bags and in several weeks have a clear pond.

I like the reusable mesh bags. Works good once all the carbon dust was washed off..

Very dusty carbon and virtually impossible to rinse. But thats not the real problem. The real problem is that I put the bag in a waterfall type filter. After 3 days, the bag disintegrated. I woke up to find my pond water dark black with a film on top making it look like an oil spill. $50 worth of batting and 4 days later, my pond has almost recovered but the bottom and all rock remain covered with black carbon powder residue.
