Is this a bad idea?

If not already mentioned, watch pH closely...turning the skimmer off like that can cause pH to drop quickly enough to cause trouble. If that happens just add a big airstone.

Christy, I'm not moving all of the 90 contents in, and in fact wasn't moving much other than 2 rocks with lots of corals growing on it. But, I can add a fair bit to the new sump, just not all. The rock I'm using should be able to catch up quickly, it's been cooking with food source for over a month.

Mindy, yes, O2 content will be something to watch with the skimmer offline...

Progress report. 180 full, salt added, the sump is setup with my skimmer, the sump for the 90 got shut down last night. I've added some rock to the new setup (in sump). Waiting for temp to come up.

Meanwhile, back in the 90 (without sump or skimmer), my 3 clams decided this afternoon was a good time to spawn. Currently, I can't see the fish....big sigh, didn't see that one coming. Setting up for a water change now, and going to the expidited move schedule, hopefully starting tomorrow..

Yeah clams typically spawn when something changes in the water chemistry, they think something has changed for the worst and spawning is their attempt of spreading their seed one last time to keep the species alive. Once things stabilize they should settle down, hopefully. Just be glad they are not that big. All the clams in my last tank spawned at the same time, now that was a mess.

One was a fair size, I couldn't see in the tank for a day. The temp jumped up 5 degrees once I shut my basement sump down, which I wasn't expecting. But now I'm sort of rushed to get the fish moved over to the 180..

What's a fair size? One of mine was over a foot.
