Hello everyone, I have a 54 gal. corner reef tank for about 7 months now, been trying to read as much as I can on the subject, I have about 150 lbs of LR, green carpet, pearl bubble coral, torch coral, pogoda bowl, candy cane corals, a few differant mushrooms, cleaner shrimp, snails and hermit crabs, 1 percula clown and 2 firefish. I have 2 powerheads running, UV sterilizer, protien skimmer, carbon filter, and I do a 25% water change every 2 weeks. This is what the local pet stores has told me I needed and it seems to be working fine, I also add calcium, strodium, and iodine, is there anything else anyone could tell me I may need to add to my set up that would help my inhabitants be healthier?
