I have a 24 Gal bowfront tank at the moment while I get things done to my 75G show tank, I have left this tank up for a week with a powerhead running and added 4 pieces of Liverock, my problem seems to be that the salt is not dissolving property but my water has the 1.022 Gravity Via a hydrometer (sp?) I have one tomato clown a mandrin Goby and a Coral beauty in there but they dont seem to be doing to well, I have a HOB filter on there at the moment, the water was run through a RO/DI Prior to being mixed with the salt mixture, Is is possible that the salt has gone funny? Is that possible? anyways the Specs on the water is Temp 74.2 Degrees 1.022 Gravity 0 nitrates (both) ammonia o as the cycle hasnt even started yet? I hope I get better responces over here, the marine newbie section has little help..
