IRON in pool - thought I had it licked...

Thanks, Watermom. I'm taking a sample to be tested today. I've been reading the Pool Forum for a few years and have spent the past few weeks reading posts related to minerals in the water. The Blue Shield Sani Shock 2 Super Shock Treatment (1 lb. bag) contains: calcium hypochlorite - 47.6%, other ingredients (not listed) - 52.4%, minimum available chlorine - 45%.

Gotta be quick, but:

#1 - Metal treatments don't remove metals, they just temporarily make them soluble again.
#2 - The way to get metal out is to filter it out (the brown stuff, in your case), so run your filter 24/7 for the next 2 weeks.
#3 - Today, if you can, vacuum, brush, and add a metal treatment. Remember, only the stuff on your filter is removed.
#4 - Use a couple of chlorine tabs in the skimmer -- this tends to drop the metal out where you want it, in the filter not the pool!
BUT NEVER EVER LET Cal hypo (shock) touch trichlor tabs. Bad things WILL happen!
#5 - Get some polyquat, and use it. This will let you keep your pool algae free, as you slowly (over 1 - 2 weeks) bring your chlorine up to get the algae out.

What you are trying to do is clean up what's dropped, get the rest back into solution, and then GRADUALLY bring it out on your filter.
