Please forgive me for reviving this old thread! A simple question, with no need for lengthy explanation...I have a heavily stocked 120 with a large amount of rock, fish and softies and a good skimmer in my sump. Which products should I purchase to most effectively reduce nitrate and phosphate? I have 3 brightwell aquatics Xport NO3 in my sump and have been dosing Pro Bio F for a week. One more: will Pro Bio F work on its own?
Thanks.
