What does this product claim to contain, is it a phytoplankton food?
Given Acropora/Montipora aren't known to be big plant-eaters/phyto-consumers ... I aim more for small-particle meaty foods [like I get out of my homemade fish food].
Some love suppliments, supplimental foods ... some folks have good success without. IMO, provided your water quality is kept high - experiment with foods, read about foods + find what works best for you.
