I wouldn't use ChemiClean either.
When nitrification takes place (ammonia to nitrate), alkalinity is bound up. When denitrification takes place (bacteria eating a carbon source and reducing nitrate and phosphate) they release that alkalinity that was bound up. A sudden drop in nutrients from the bacteria bloom could be the reason why you're seeing this increase in alkalinity. As the alkalinity increases you're going to get calcium precipitation which will lower the calcium even more, and cause the alkalinity to go up further. I would suggest a waterchange with a lower alkalinity salt mix such as Aquaforest. I would add extra calcium to the saltwater while doing the waterchange. IME, calcium can increase by about 50 ppm per day without irritating anything. Alkalinity swings are a real problem though. In your case, the damage has probably already been done. Instant Ocean or Reef Crystals isn't going to help you out much here.

Cause and effect, I have never heard of anyone using calcium glucomate as a calcium dosing source.
Definately stop dosing the alk and perform a couple larger waterchanges to bring the alk down to 9, and in future use calcium chloride for dosing calcium. If you want to dose a bacteria source use vinegar in really small amounts but generally I've tried to stay away from carbon dosing because it brings some weird strains of bacteria out.

IIRC? - which means?
I use Kent salt mix which has a kH of 7. I can't remember the rest when I added the first 220 gallons of water to the system. I think Ca and Mg were natural seawater parameters. I am going to wait until Ca rises with use of Turbo Calcium as Myka suggested - let things settle down a bit before I do a water change. I guess I will have to be very, very patient to wait for the slime to disappear over several spaced out water changes. AquaAddict

Update
Just wanted thank everybody for going to the trouble to give me some great advice.
My ca level is up to 440 now and alk is down to 11.5. There is still a lot of fuzzy slime but I am slowly tooth brushing and netting a little at a time mostly to save my back. Strangely enough the corals most affected are the Euphylia, followed by the Calaustria, and then the Duncan coral. My lavender poccis and purple poccis don't seem to care but the green pocci's have browned out. The zoas are fine as well. AquaAddict

Well that sounds good. You're on the right track. The slime should go away on it's own, but yeah it may take a few weeks. If would be great if you could post a photo though. Sometimes things aren't as they seem.
