Review on Nitra-Zorb Aquarium Canister Filter Filtration Pouch - Size 6, 1-Count Bag (2-pack) by Alquino Scarwin

Amazing product! I have a 2500 gallon carp pond with a nitrate problem, the nitrate level in my pond was 160ppm. I tried several things and none of them worked. I haven't changed a ton of water in 3 months and it still hasn't lowered my nitrates. So I set about fixing the problem and within 24 hours my nitrate levels went from 160ppm to 40ppm. I opted for a 10% water change and measured my nitrate levels 3 hours later; Within 27 hours of using Nitra-Zob in my pond the nitrate levels went from 160ppm to 5ppm. Amazing product! I wish I had found this material sooner and maybe saved 4 expensive carp from dying of stomach ulcers which are usually due to water issues like mine.
