Freaking OUT! Brown stains on my gunite pool!

[PoolDoc]

Hi Amy;

You can shock your pool with bleach -- 3 gallons of PLAIN 6% household bleach will do it, unless your CYA level is high. (Did you ever get a K2006?)

Regarding the CuLater, we recently got a bit more evidence that that work. So, if you don't mind the expense, keeping one in your skimmer will reduce the likelihood of an recurrence of your stains. And, it should last till it is used up, if you keep it from getting contaminated with pool goo, so remember to get skimmer socks, if you get the Culator.. I wouldn't depend on one to last more than a season, though. You can get the small one, if you like, since you may not even have any iron. If it DOES begin collecting iron, it will discolor.

You *really* need a K2006, even if you don't use it regularly. I don't know what your TA, CH, or CYA levels are, so I can't advise you as well as I'd like.

Also, if you'd please complete our new Pool Chart form -- it takes about 30 seconds -- we can answer your questions more appropriately.

And, one more thing: you did the bucket test, on your pool, right? If so, you should ALSO do it on your tap water, to see if there are metals in the water you are adding to your pool!
