Bah, it's growing back on the rock again. It's not red, though, like most cyano
that i'm reading about. It's dark green.
I started a phosguard run yesterday, so hopefully that'll kick it in the pants. I need to get a salifert PO4
test, too, since my API test kit doesn't have the resolution required (goes from 0 to 0.25 ppm
), so I could have had high PO4
and it just didn't register w/ the kit.
I'm pondering the thought of turning off the lights for a few days, too. I have duncans, torch, frogspawn and zoas...they should be OK for 72 hours of no light, right? The room has ambient light in it during the day, so it won't be complete darkness.
