I just started using zeofood 7 recently and it seems that my blue and purple acro has gotten more purple further down the tips and the blue has moved further into the body. Its looking better than it ever has. I also dose Pohl's Coral Vitalizer, Sponge Power, Jod Complex, Seachem Reef Plus(GARF swears by it), and Kent Essential Elements. I first started with the CV and it worked wonders so Iv'e slowly been adding more of their products over time. Thing were looking great even before I started with the Food 7 but not my corals are looking even brights and gaining coloration that they didnt have before. I soon plan to add Pohl's Extra to my dosing regement, based on what it says on the label and my previous experience with the Zeo products I expect good results.
