Since I started feeding my coral with polyplab reef roids I'm super happy with the progress. The colors are way more vibrant and some corals including my mushroom colony are getting new crazy colors in them that they never had. Growth is extensive as well and I'm roughly 2 months into using reef roids. I highly recommend using this product. I'm looking at purchasing the polyplabs polyp booster next which is like $22 but after that I'd like to try the COLORS treatment from polyplab that is supposed to make colors more intense and vibrant in corals, only problem is that it's like $60 for a small eye dropper bottle.
