Algae help needed

[Razor Ramon]

To help aid in stability I would make sure your water source is good and do weekly water changes till you get the tank stable .
Testing water is always good to do but chasing numbers at this point with dosing is a bit much . I have had many coral tanks and added nothing except doing weekly water changes . Yes when the lps and sps get big then dosing calcium and alkalinity or calcium reactors are needed.
