I'm trying corals for the 1st time and I have 1 frag each of Bambams, eagle eyes and 2 others that i'm not sure the names of them. Bought them about a month ago and the eagle eyes are open the bambams were open now only half of them and the others dont seem to want to open up.. well I can kinda see a lil color so maybe %10 open. I have tried to move them around and get them out of the water flow and a few other places around the tank but still no luck.. It is a 30G bio cube with the standard lighting it came with.. 36W power compacts.. 10k white and the Actinic and the blue led moon lights.. my sg is 1.025 trites and trates are 0, PH is perfect and ammonia is weird.. it reads .50 added ammo lock still read .50 2 days later added ammo lock again and same reading.. Asked about it at local store and they told me that the ammo lock detoxifies the ammonia but may give false readings when testing for it. temp is 78-80.. any ideas what I could do? better lighting maybe? I need help and dont know what to do..
