Help!
Ok, so my tank has been running for about 6 months. Coral growth is good fish are healthy but I have cyano and green hair algae lights are hydra 32 on 8 hours a day
Does all for reef every day
Fuel and reef roids twice a week about half what is suggested. A mix of frozen and dried food.
Water changes 5 gallons a week just for the water that I use tested with a TDS and meter and it was 6.
Alk9-10 it swings from med 9 to high 9
Mag 1320 +/-
CA 400
Nitrate O
Phosphate 0-0.03 /-
Filtration is a sponge filter
Proteins skimmer
And small refugium with chaeto
This photo was taken with white lights my question is how do I start getting this under control?
Someone said to try chemiclean elite. What are your thoughts on this? I have feeling that my p03/4 are not really zero and its only the algae that's make it look that way.

I would raise your nitrates and phosphates off of 0. How are you testing?

What does your CUC look like?

Its not bad to be honest, its a good looking tank.

My thought is that you have low flow going through that pile of rocks, detritus settles and algae grows. Try to find a way to increase the flow through that pile of rock.

And secondly get more snails, I don't see many, get some turbo's.
