Brightwell Aquatics Xport NO3, ultra-activated denitrification media with superior performance characteristics, 300g (10.5oz)

it has done nothing yet.

Been using for weeks now and no noticeable difference. Did everything as instructed, and nothing. Dont waste your time or money

Lowered my nitrate from 20 to 5 in two days. Pretty expensive though. Just rinse, place in filter bag and drop in sock.
