Algae Barn was out of Chaeto for a long time so I went with Ulva instead in my refugium. The Ulva is growing well, but noticed that the small pieces were clogging my sump bubble filter so I put a piece of egg crate and screen in my refugium to prevent this from happening. This is working fairly well, but I am noticing a bloom of what looks like ulva growing from the rocks in my DT. It that a thing? The tangs seem to be nipping at it here and there, but not enough to keep it back. The PO4 levels in the tank were a bit high .17ppm and I have brought it down to .04-.07 with the refugium and BRS GFO. Is the only way to stop it to lower the phosphates even more? I am turning my refugium on longer and with more intensity to help, but in the meantime what else should I do? I didn't realize that this would be a problem. Perhaps this isn't a problem? The tank is about 4 months old... I also tried Vibrant and that doesn't seem to be doing anything to it
Any thoughts?
Thanks in advance!
