I have been to several LFS and it's not helping and been told 2 different versions of whats happening. One store gave me Reef Fusion parts 1 &2 and then my corals started dying (frogspawn types) took water to another LFS and he said calcium too high and they dying from burn. I removed them type corals and moved to my 75 gallon tank and was able to save a few. Did water change and install a different protien skimmer(LFS #2) it is a coralife 125g (that store said it was a protien algae outbreak and the instant ocean one i had is garbage. and was sold TLC biological clarifier marine S.A.T.
