I deleted Dave's post, suggesting bleach, because I think you are still planning to clean up the water mold, and then stick with Baquacil to avoid airborne corrosion, since your pool is indoors.

If that's still the case, use polyquat, not bleach. For your 24K gallon pool, I'd recommend 1 quart to start, and then 1 cup every 3 days. Dilute it in multiple gallons of water, and then pour it all around your pool. (Use the link for more info about polyquat!)

Also, with the pump off for several days, and the polyquat in the water, you may settle out some goop. Plan to vacuum carefully, when you first start up, if there is debris, dust or film on the bottom. You may want to re-align your return eyeballs so they don't stir it up, before you can vacuum it up!
