A golf ball coral is a Favia Fragum, I do not see many people using phyto for LPS, most people are using a Amino Acid and a broader spectrum coral food like Coral Frenzy or Reef Roids. I would do some research on how Phtyo works, but I do not use it in my tank. I absolutely would not use as much as was recommended in a tank that is cycling and has no softies or acros and very few LPS or filter feeders. Here is my Favia as a reference point.
