Kent uses Calcium gluconate too IIRC.

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.

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.

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.

If I Recall Correctly

I would love to post pictures but Photobucket won't download. I can upload pictures to PhotoBucket but I can't get them out again.

You mean Kent puts Calcium Gluconate in their salt mix? Aaargh!, I just bought 2 buckets! No big water changes now I guess. Kent's declared salt parameters are higher that what they turned out to be for my first fill up.

Kent Salt
 

I emailed the Kent guys and they say they don't put calcium gluconate in their salt mix.

slime update
 

Hi Everybody,

I followed Myka's advice (thankyou, thankyou, thankyou). The slime is gone. Ca is 440 (was 460), Mg - 1470, kH - 7.7.

Corals have mostly recovered but I lost 3 flasher wrasses, 2 anthias. The loss may be due the bacteria or stress from me doing so much manual removal of the slime. However, I feel fortunate that Myka's advice worked so quickly. Things could have been so much worse.

Sorry to hear about your fish losses, good to know your tank is back on track.
