Tank has been setup for 4 years. 90 gal. 10 gal. Sump, rapid led reef kit lights, plenty water flow, and agressive skimming.
Waterchange 15-20 gal. By weekly
Corals- Duncan, torch, orange cap, spongodas, orange setosa, red planet acro, 3 different bird nest, 3 more monti's and some racordias.
All look well and grow but no to very little polyp extension except, Duncan and birdnest . And all info I've found says not to worry about polyp as long as colony is healthy.
I've tried to add new corals over the past 16 months with little success due to deflating or retracting polyps and slowly beaching.(example I have an acan frag completely deflated for 2 months with slight bleaching on edge.)
Water chemistry as of today-
Ph-8.2
Alk-10 meq/L
Phosphate <0.25
No3-<5
Mag- 1200
Cal-400
Salinity- 1.023/30
Any advise would be helpful I've exhausted all the local fish stores. Thanks
