Well I am happy to say my algae is slowly receding, I am still trying to figure what the cause is. My parameters are okay, nitrate and phosphate could be a little lower but this is what my tank wants to stabilize at, nitrate 25ppm +/-3, phosphate varies 0.21 - 0.14. When I started to lower phosphate a little it seemed to get worse, so I will just let it ride for now.
I have a mixed reef and I am surprised I have a couple sps corals that are doing well and growing. For a couple years now my duncans refuse to come out, they come out a little and I guess they don't like the water and go back in. Was doing weekly water changes of 10 gallons, then for several months I tried one WC every 6-8 weeks. I have to go back to weekly water changes because of the algae and some corals dying.
