Hello, I need some serious help. I purchased a 125gal reef setup about five months ago and it had healthy fish and softies doing really well. Unfortunately the move killed everything. I allowed the tank to cycle until the parameters came back good and started adding livestock. First hermit crabs, horseshoe crabs and fish. All did well. Then I added corals. They died. I rechecked parameters and added a few more frags. They died. I checked the parameters again, fished out anything that even looked dead, though my water was good and my fish growing like weeds. Waited a week, added a few more corals. They all died. Finally, I went into a LFS and asked for unkillable corals. I came back with seven frags. Added them to my tank and they started to open, then closed up and now look like they are declining, ready to die! Fish are still great, parameters are good! I am so upset since I only wanted a SW aquarium to have coral! 125 gal, with 2 red sea canisters, 250lbs live rock. Parameters: Spec. Gravity: 1.024 (was at 1.026 but LFS said to lower it as I am using a hydrometer and if it was off I could have too high of a salinity. Lowered the spec. gravity slowly over three days, been at this level for 24 hours, no improvement) Temp: 79 degrees pH: 8.2 Ammonia, Nitrite, Phosphate: 0 ppm Nitrates: 5 ppm Ca: 460 ppm kH: 179 ppm I have two blue jaw triggers, sixline wrasse, coral beauty angel, two yellow tail damsels, purple firefish goby, percula clown, lawnmower blenny, two engineer gobies. I have about five or so blue legged hermit crabs, and three baby horseshoe crabs. The corals are a zoa colony that hasn't opened since I added it, another zoa frag that only partially opened and then closed for good. Two softies I don't know the names of that are droopy and closed and three hard corals that have bleached out and revealed their skeletons. They all still have some color but not much left. Please help. I tried researching why this keeps happening but haven't found anything that addresses every coral dying while the fish seem perfectly fine!
