Ok, now I hijack. I tried this starve the algae of nutrients trick a long time ago. I ended up starving fish too.
How are you supposed to starve a tank of nutrients that feed algae if you are feeding Rod Food to the fish and corals??? And yes, I have a cleanup crew (see other threads), and a fuge (which grows hair algae more than any other algae), and run carbon and purigen and a mammoth skimmer blah, blah, blah...
Contradictory demands, it seems to me...
