When I removed a large chunk of my sukarnoi, mine shot up just over 10dkh. I just stopped dosing kalk at night and turned down my reactor. I let it come back down on its own for two weeks. Who knows if it took a day or two days to climb that high? I didn't test until a couple days after removing the sukarnoi. I've never had an issue with alk rising or lowering, but I've had issues with nutrients doing the same.
Yeah, I really wanted to go to CFM, but when my power went out, I didn't want to risk not being home if something else happened. As it was, 44hrs without power really sucked. I'm just glad I had a gennie running the whole time, but wish I had turned on my LED bars for a while each day.
Anyway, check out corals.com or pacific east aquaculture for clams. There's a new guy in Woodland Hills that has clams, mostly maximas now, but I think he gets in different ones as well. His site is Reef Exclusive. I'm going to try and stop by his place this week and check it out. I've been eyeing one of his maximas for a while. I know Vivid gets in clams on a regular basis now, both wild caught (which I stay away from) and ORA clams. The only wild caught clams that I'll buy are noae (teardrop). If I see any squammies out there, I'll let you know. I'm looking for some small croceas and a purple/gold maxima (or another noae if I can find one?).
