Back again to discuss action I have taken because of the very high phosphate problem. Now for 3-4 months I have been using nothing but RO water from my LFS. All added water is RO. Have checked the level of phosphate in my barrel of RO, very little and none since the LFS has put in new filters. However, after a few hours in my tank, the phosphate tests show it is back up to what it has always been . Algea problem has only worsened. Clean every day. Corals all look great, fish are healthy,even have had Clarkii's spawn a mass of eggs, don't even have that many fish in the tank anymore, Have taken out all the very large ones and sold them back to LFS. Can the corals and rock be leaching back into the system? Have had the orange cup sun coral thriving in my tank for about 4 months now. Was told that they can not take high phosphate levels. I would love an educated response. Purchased the sun coral at Saltwater.com and it is gorgeous and building new cups. Has doubled. Didn't know they grow so rapidly. How does it do so well in high phosphate?
