Hi, I’ve had green hair algae pop up go away and pop up 2x now in my tank. The first time I did a massive water change, scrubbed everything that touches water in my tank, and got all new filter media. It’s now back and has been for about 2 months. I brush parts of my rock off and have been doing 25% water changes weekly. It won’t stop growing and I know for a fact that I haven’t been over feeding. My light schedule for the last 2 months has been at max 6-7 hours a day. It has started to bother my zoas and I need to stop it. How concerned should I be for my corals? Willing to spend a good chunk of money to make this go away, any equipment suggestions?
My setup (very simple)
37 g cube
Fluval 206 canister filter
Pp4 jebau propeller pump
Philzon 165w led light
Heater?
water parameters (api test kit) and ice cap pocket tester
Temp - 78
Salinity - 1.024
Ph - around 8.35
Nitrite - 0 ppm
Nitrate - O ppm
Phosphate - no way to test
I turned the white light up to show green hair algae in pic
