DKoKoMan's 150g Reef Tank

What's the po4 and no3 reading.

Typically if those above are higher more alk and ca won't hurt the tank.

If your alk is that high your sps is probably not consuming enough alk, this could be due to a couple reasons... when po4 is high sps has a harder time soaking up bicarb but if the alk and nutrients are high then they are able to use it up.

I usually run alk at 8.5-9.5 and po4 is higher like .17 to .25 I notice alk is depleted slower so I dose about 80ml per day but when po4 is dropped below 10 then alk is 95ml per day....

Mind you ca is over 500 and mg over 1600.
