I have been suffering with Red Nuisance algae (Cyno ) & Brown Algae on the sand for months. Restarted tank last December. Red Sea Reefer 750. @ 16 fish. I have used chemiclean, red goes away & comes back. Water changes using ro/di water. No help. Nitrates at 19.5, Phos .08. Salinity .25, Mag 1335, Calc 425, Alk 8.45. Stable.
I used floss in filter cups for mechanical filtration & large skimmer. Temp 77.3-78.5. ESV 2 Part on dosers. Some growth but tank ugly on sand only. 3 Eco Tech Pros with 4 ATI t-5 bulbs.
2 Blue, 2 Coral. Using co2 scubber. Have refugium that tends not to grow much ans always has red cyno in it.
Main issue is to rid most algae on sand. Is my Nitrates & phos too high? Can that cause this issue? I am constantly fighting this. Do water changes every 3 weeks of 20%.
Any ideas what I should do or use.?
