It is back within two weeks of a Chemiclean 48 hour treatment. Flow is good, tank not over fed, lighting appears ok, Nitrates and Phosphates are in order. Only thing I can think of it’ll my G3 Pros are 3-4 years old. How do you check the spectrum on the lights? Any other thoughts?
Cyanobacteria
- Thread starter asunshine
- Start date
How old is the system? How old are your r/o filters?
Same tank as refugium issues, no longer growing chaeto? Have you done any ICP tests?
You could try adding some beneficial bacteria like something from Dr Tim's. Even though test results are all showing good, in my experience cyano is usually due to nutrition being out of whack, the flow is supposed to export waste that's why people suggest adding flow. My thoughts are that the is nutrients are in your substrate, only bacteria could help if that's the case.
I highly doubt its your lights. I usually deal with cyano by vacuuming it out with a 1/4” hose a few times a week. Usually tanks a little over a month to clear it out. I agree with @bhodges82 and it usually appears with some imbalance of nutrients that it feeds on.
