Covering up Zoa?

[vadryn]

Is this basic algae covering up my zoas? Seems overly aggressive. Want to treat appropriately

Does it brush off easily? Could be a green cyano

It seems to. My low nitrate is new. Working on goals dosing to supplement if not replace my in tank refugium and finally t the point where I don’t need my fuge light on 24/7

Vodka dosing

I would try and get the algae issue under control before dosing. Algae could throw off your actual numbers. I like to use a turkey baster and blow all that stuff off and put filterfloss in overflow to remove as much as possible followed by water change.

I haven't had an algae issue until recently. I'm trying to hopefully get to the point where vodka dosing can replace my in-tank refugium. So the instability is mine... and expected while I try to dial things in. I've stopped running my fuge light 24/7 since my nitrates bottomed out last week. Last 35% WC was 4 days ago. Todays numbers are:

Alk - 11.9 (Red Sea Pro)
Nitrate - 5.7
Phos - .15
Salinity - 35
