Been battling diatoms for over a month, my tank is four months old, nitrates are zero, phosphates are 0.0 -Hanna, but I'm know that they could be up to .04, using extra gfo, feeding less light cycle down, added like 40 extra snails all different sizes but cant get rid of it, 20% weekly water changes, I'm thinking that this brown algae is consuming nitrates so that's I'm getting a zero measurement, so I was wondering if upping my dose might deplete the nitrates before they are consumed by the algae, I only have lps in the tank and they are all fine, anyone done this before??
