I have been battling hair algae for probably over a couple months now in my 60 gal. I first noticed it popping up following a cyano outbreak where it began growing literally underneath the cyano. There is currently no cyano but the hair algae has nearly covered all rock work and even growing on my GSP.
My CUC consists of about 8 turbos, 6 trochus, a handful of blue and scarlet hermits, a tuxedo urchin, and a tiger conch. I run a skimmer and UV sterilizer. Lights are on for 9 hours and I have a refugium with chaeto. I have been manually removing as much as possible as some areas can’t be reach but the hair algae returns very quickly. I tried 1 dose of reef flux which only seemed to upset my coral. Since then my coral have bounced back and look happy with the exception my GSP ironically. My parameters are as follows:
Na: 1.026
NO3: 2.1 (Hanna)
PO4: 0 (Hanna) usually 0.02-.04
Alk: 8.6 (Hanna)
Ca: 427 (Hanna)
Ph: 8.2-8.3
Temp: 79 - 80
I do dose nitrates and phos as they have always been on the lower side and I’d like to avoid dinos. If I missed any info feel free to ask! Any advice would be greatly appreciated. Thank you
