Tank is about 4 months old and has been through diatoms then cyano
, now bryopsis. I think there is some hair algae mixed in, but it definitely is bryopsis mostly.
Water is RO
Ammonia, Nitrites are zero
Nitrates are about 5 in between bi-weekly water changes
I've been removing it by hand, but it grows back in a matter of days. I've cut feeding down to once per day and lights to about 6 hours.
Any suggestions? The lawnmover Blenny isn't touching the stuff.
