Update: after cleaning tank up bit and water change thought I'd update. Chaeto is growing crazy. I've already given 2 baseball chunks to local reefers trying it out in aio like the wb20. I added 2 corals, 1 2headed octospawn and large mushroom from local folks. Parameters after the 5gal change look great except nitrate is bit high, but been reading zoas and euphyllia like the octospawn enjoy that as well my nem like a little phos and nitrate to help it grow. Still trying to dial in my hd prime as I can't seem to get eight colors to see the blues and greens in the corals. Anyway that is all. Happy reefing!
