I hate to give up but just no success with SPS
corals. Most recently bought 5 SPS
frags two months ago and none are doing good and almost dead, I think. I believe I have all the right equipment to be successful which is why I'm so frustrated.
My system has been running for about 4 years and consists of a 120G with built in overflows plumbed to a 55G sump in the basement. (2) Poseidon PS4 return pumps. (2)-250W MH
lights and (2)-75W actinics. MH
's on for 8 hours and actinics for 12. EV180 protein skimmer. 1 tunze 6060 and 1 hydor koralia 4 powerheads. RO
water is used. Auto top off with kalkwasser mixture. Tropic marin salt.
Water parameters using Salifert test kit: SG
1.024, Calc 400 ppm
, Ammonia & Nitrates & phosphates 0, Ph ranges from 8.1 to 8.5 measured with probe, temp is maintained between 78-79 F using heaters and homemade chiller.
