Brightwell Aquatics ABABAC500 Microbacter7 Liquid Water Conditioners for Aquarium, 17-Ounce

I bought this MB7 after reading about it on a local reef message board. People say using this will help lower nitrates as it helps boost the benificial bacterial in the aquarium that consumes nitrates. I've been using it for a few weeks now and it does seem to be helping lower my nitrates.
