ok..for almost 2 yrs I have had little problems with my sps..had a nice collection of montis, acros, and milles..then in the last three months all hell broke looseand my sps have been dropping like flies..now my red planet has bit the dust and I am out of ideas of how to stop this..since Christmas I have been performing weekly water changes, weekly PO4 changes, any other maintenance issues that arise..I use distilled water for top off and mixing..I use Red Sea coral pro salt..I dose 3 part alk, calc, and mag..my PH is 8.2, my alk floats around 9, and mag around 1400..PO4 is not detectable on my tests..also in the last 3 months I have had a serious issue with red slime..never had an issue with red slime before..but here recently it has really began to diminish..basically my sps begin to bleach at the base and tips and shortly after they are gone..what is going on ..I am not knew to the game..I have been in the hobby for 12yrs..the tank I currently have has been up and running for 3 yrs..any ideas would be great..
