OK so let me think. Thursday, I added that CUC order of aquilonastra, micro brittles, chitons, stomatellas, and collonistas. The micro brittles are so cool, if they weren't so expensive I'd buy more. although my provider says don't worry, they'll reproduce...
that night I added a dose of chemi clean. Saturday night would have been 24hrs but I waited till Sunday morning to do a 20% WC. the chemi clean helped, but didn't do "everything. so I did my water change, and added anoter dose of chemiclean (I read it was OK to run another one). I vaccumed the sand, cleaned, etc, dosed. went to the gym. came back a few hours later and the sand was already rusty again.
I took my nero power heads and blew off all the rock work, the detritus around my zoas etc. I felt like such a moron for not having done that earlier!! it kicked up a heck of a mess so I did 1/3, let the water clear, did another 1/3, etc. almost immediately the zoas, duncans, and gorgonians started opening up. I have no idea why I didn't do that the first time. I need to be better about that!
