API ACCU-CLEAR Freshwater Aquarium Water Clarifier 8-Ounce Bottle

This stuff is great. My son was having trouble with his fish tank getting extremely cloudy, even after we did a full clean and water change it wasn’t long until it was cloudy again. All levels tested normal but obviously something is wrong. (I think I may have figured it out though).But in the meantime we used this product while we were trying to figure out and it did end up working. It took a few doses over a few days, but I’m very pleased. Hopefully I’ve got the problem figured out, but I at least know I have this product to help us out. ?
