Tank is over a year old and has been looking fine up until about a month or so ago. I've been fighting this algae for a while now. About 2-3 months since the tank looked good. I have hair algae that have popped up everywhere and brown algae on the sand bed. I tried chemi-clean, then I have done a 3-day blackout, several 20% water changes, and did a two-week treatment of microbacter clean and razor together. Manual scrubbing and removal. I don't know what else to do. I've lost about $1000 in coral fighting this and the rest don't look good. I'm at my wit's end and about ready to leave the hobby for a while. I routinely find my nitrate bottomed out regardless of how much I feed and supplement. Have added neonitro many times to keep no3 around 5-10. Attached are some pics of the parameters I just checked as well as pictures of the tank. Any help would be appreciated.
