hm-mh.

Retest that CYA, using a 50:50 pool water / tap water sample, and then multiplying by 2.

[mrszaff]

ok, before I multiply it's not quite at 50 so about 52which makes it 104 after I mult by 2
I know that's high....

[PoolDoc]

OK.

It will be sort of expensive, but if get the pool cleaned up is the priority do this:

1. Buy whichever granular product cleared the stains fastest and was cheapest. (Your chlorine is going to break them down anyhow!)

2. Apply it as best you can, directly to the stains. One possible way would be to take a 2 gallon freezer bag, put 1/2 pound of stain remover in it, add 2 cups of water, and then a medium wash cloth. Saturate the wash cloth in the concentrated slurry, and then close the bag, after forcing the air out. Get into the pool with the bag, and open it NEXT to a stained area, and wipe the area down. That way, you may be able to use the bag to avoid a lot of the mixing and dilution with pool water that would otherwise occur. You probably want to wear gloves to avoid concentrated exposure to the acid.

3. As before, make sure your pump and filter are working well. What will happens is that the metal + the citric or ascorbic acid will go into the pool water, and encounter the chlorine. This will break down the organic acid, releasing the metal -- which will hopefully then end up on the filter BEFORE it can stain the pool again.

4. Don't let folks submerge their heads or get their eyes in this water for 24 hours afterwards, if you use citric acid. It initially forms some irritating products with chlorine.

5. Don't worry about your chlorine level, till it gets near 7 or 8. At that point, you'll need to begin adding chlorine again. Do brush any areas of algae BEFORE starting all this.

should I worry about my cya or ph etc, yet?

cant get in the pool to to do this because the staining is at the bottom of the deep end, so ill just try to throw it in there better i guess..or buy vit c tabs and throw those
thanks again for helping!
Ill keep you posted

[PoolDoc]

or buy vit c tabs and throw those

Sams Club has some great big bottles of Vit. C tabs that are pretty inexpensive. Tabs wouldn't dissolve as quickly as the granular, so that might work. I'd be interested to know if it does -- other people might want to try it.

It's working, thanks!
