That seems to be the wisest move for now. Having read more of Tullock's Marine Chemistry book, I'd have lots of questions anyway before restarting it.
With the water changes we've done recently, I took a chance this morning, and dosed some Magnesium and some Calcium. Both levels went up noticeably, so the water is in decent shape, despite an Alk of 13. The Ca went to 480, so I'm going to leave that alone and test daily to make sure it doesn't drop off, and with Mg at 1230, continue to dose that until it come up to around 1400 or so, and keep it there by monitoring.
Daily Alk testing will probably tell me how the water is doing - if there's a rise in the Alk, then I probably still need to do some more water changing until it comes down to around 10, but am trying to avoid changing too much water to keep the systems stable. Nitrates are staying around 0, and we're keeping the skimmer watery to ensure it errs on the side of removal of all nitrates for now, since we've accepted that we're heavily stocked on fish. (There, Becky, I said it!) I'm also keeping a powerhead in the fuge, injecting air (therefore oxygen) into the fuge and at least adjusting the system for heavy bioload.
(Boomer, if you're reading this, please tell me if I'm learning something....)
