Default cant keep cheato alive

Hey everyone,

I need some help / advice with cheato algae. I have a 180g with 33g sump. Sump has a dsb with cheato floating on top. Flow thru sump is about 500gph. I use a 13W coil type fluorescent bulb from home depot. Light is on 24/7 and about 3-4 inches above algae. I use a calcium reactor, a little ozone with carbon, and I add a bit of kalk to the top off water.

The small amount of grape caulerpa that I have is growing like there’s no tomorrow, however, the cheato is turning white and crusty on top. Underneath, it’s still green, but grows slowly. Top looks almost like it’s bleaching. About a week ago I added a powerhead to increase flow, but no improvement. Now, it looks like there’s fuzzy green algae growing on top of the cheato. Could it be the pH swing from the kalk? Too much light? Too much iron? Not enough iron? Still not enough flow?

Thanks guys.
