Ok, noticed my pumps were starting to get bogged down, and they haven't been cleaned any time recently, so cleaned them this evening thoroughly and topped off the tank, did all the tests I have except Mg, and put the anemone back in that crevice, and shoved some bits of LR in the side to hopefully keep it from crawling out.
Tests came back:
SpG 1.027
Ph 8.4
Calcium 400
Nitrate 0 (or undetectable)
dKH between 9 and 10 (closer to 9)
took a few pictures of where I put him back, plumbing bit is still there to keep him from tipping forwards, but I moved it up a little so it's not touching him, that might have ****ed him off last time, who knows.
