can someone please tell me what mushrooms live on? What chem? I am new to reef and I would love to get some to grow. I got a rock with one on it and it has done nothing. (3months) I have a great looking gorgonia and a few healthy feather dusters. I also have had a BTA for about 4 months and it is doing ok, some days very nice others it is not happy. I also have a coral but I have no Idea what it is. I know it is soft and it is on the rock the mushroom came on. It is doing great seems to be growing a little but not like it should. I think my real problem is my Nitrates are always high. I cant seem to keep them down no matter how often I change the water( using RO every time, and IO salt). I have always been told mushrooms are easy to keep. (by high I mean Nitrates show between 40 and 80 ppm on my "saltwater master liquid test kit ) Calcium is high ( 450 last test ) Alk on target, and ph 8.2. I have a 110g long with 4, 96watt PC 2, 10K and 2 Actinic. This should be good enough to grow shrooms right? any help or advise would be great. I really would love to have some shrooms and soft polyps spreading across my tank. Please tell me the easiest to grow and keep. If anyone is selling some I would love a chance to buy some healthy ones.
