My name is Josh. I'm in NE CR on the West end of Blairs Ferry Rd out towards Palo. I have a 210. Ordered most of what I have from GARF and have been pretty happy with it. I have some clowns and anenemones. Looking to get rid of one clown (cinomon that is hosting in my long T but my Clarki was there first and took better care of it). I try to keep a good natural balance. Not sure if the sulphur denitrator is natrual or an unnatural of being natural but I've just added it to the tank with good results after some floods and rotton egg smells that I think are all worked out. The nitrates dropped so fast I think my soft tree corals did not like it. They have been small and droopy ever since it kicked in. Although the main piece that the others dropped from seemed to be acting this way before it. Which leads me to my first question for the group. It what point will High Calcium start to cause ill affects? Tests say upper 500's. I also have lots of extra Reef Rock. Biger sized pieces that are good for shelves and tables. Let me know if you would like to work out a trade. There is probably 50-100 lbs. It is not all in my tank. Most has been sitting in tubs of old reef water. They are not gross though. Pretty clean. Lost a lot of Pink that they originally had. It might come back.
