I have a 200 gallon fish tank for quadraphonic gardening inside a green house. I was going through API Ammonia Lock quite extensively. This product really works well and is less expensive because one can regenerate the pads with API salt. I really appreciated the lower cost (in bulk) - the free shipping - and the quick delivery. On a scale of 10 with 10 being an A+ - I give Pet Mountain a 10 and this product a 10.
Wow finally I found something that really works - my nitrates are at zero. l tried other products to lower nitrates, did not work, I ordered two pouches and they keep my water crystal clear and my nitrates at zero. I will be ordering more. The service at PetMountain and fast shipping are the best and the prices are way better than any other store.
Fits like a glove in my API filter. Dropped my nitrate levels down 4 points in just 1 night so far. Good stuff for busy people like me who can't do water changes as frequently as we would like.
I have Pearlscale and Oranda Goldfish. This stuff has greatly improved the water quality for longer periods of time.
