I have a problem of keeping my Xenia alive as they do well in the first month then refuse to open up then wither away. My current one is showing signs of that. All other corals (open brain, colt, frog spawn, hammer heads, tree, toadstool, candy cane, deadman fingers) are doing well. The Xenia is not placed anywhere near others. I do PWC
20 gallons every two weeks in my 125 gallon with sump. I feed plankyton liquid 13 ml everyday. Water chemistry (tested weekly) and re-confirmed with LFS
1. Ammonia and nitrite are zero.
2. Nitrate is 5 ppm
. A month ago it got to 15 and was quickly corrected (no more pork chops ever since).
3. Ph is 8.3
5. Salinity is 1.025
6. Calcium is 375-425.
I have 8 T5 light bulbs with 6 @ 39 Watts and 2 @54Watts running 12 hours/day. I have 3 Kolia 3 powerheads.
I have polyfilter and phosphate mesh bags(5) placed in the sump. So with what I believe to be excellent water quality, something is making the Xenia unhappy (please don't tell me pork chops...). All the fish are thriving including the difficult to keep Powder Blue. Please advise. DP
