Additives that actually help corals.

... Okay guys, c'mon here. This is so heavily biased and misinformed.

There are plenty of additives out there that work plenty fine. Just because your corals are colorful doesn't mean they can't be MORE colorful, or colorful in different shades. Same goes for growth, polyp extension, and longterm success (especially in the case of certain Goniopora and Cespitularia.

It's so frustrating seeing people assuming that their work is complete and that no amount of tinkering or experimentation will do anything to make it "better".
