I hate dinos. Hard to get rid of. They usually outcompete other things when there's an imbalance of nitrates to phosphates. You can dose to keep them at respectable levels to grow macro algae, which does much better when both no3/po4 are constant and higher. I was able to do this, but my dinos flourished even under ideal conditions (and even with heavy dosing of DinoX). Ultimately I starved the tank out with more NoPox and things are fine. I feed a lot and 3 - 5 times a week I will spot feed my SPS with a baster with Reef Chili. I'm also dosing AcroPower to see if that helps. So far corals are healthy and colorful even without any detectable NO3/PO4 in my tests.
