Leslie Stain Remover (Ascorbic acid)

Postby Alou49 » Sun 29 May, 2011 19:07

Beware the high priced "stain remover" from Leslie pool supply! It says it treats 20,000 gallons, but in reality it only treated the pools surface the chemical touched. I double checked the required ph and alkalinity levels, and the stain remover from Leslie Pool Supply only treated small sections of my pool, and was not effective on the walls. I have ordered three 2 pound units of Stain Free from Amazon, in hopes of curing my pool staining issue.

I added about a 1,000 vitamin C tablets from my local pharmacy, they do a great job too... but the results are also surface contact only.

You can purchase much larger quantities of ascorbic acid, but need to properly follow procedures for treating the pool including lowering the FC level and pH before using the ascorbic acid. See Metals in the Water and Metal Stains for more info including places to purchase ascorbic acid in bulk.

If the initial treatment of 3 lbs of Ascorbic acid does not take care of all of the stains, do I start the process over? Or just add more AA?

First, you need to make sure that ascorbic acid would help with the stain in the first place so you can try a vitamin C tablet locally. If that works, then the broader treatment should work and if it doesn't the first time then yes you can try it again, possibly dosing higher. Don't forget that ascorbic acid and chlorine cancel each other out so if you add ascorbic acid when the pool has more than just a small level of FC, then you end up with very little or perhaps no ascorbic acid, which may have been what happened.

While iron stains are most readily removed by ascorbic acid, copper stains can be more difficult and of course stains that aren't metal, such as organic stains, won't be affected much by ascorbic acid (organic stains will fade from chlorine, including a Trichor puck rubbed on them for plaster pools -- do not ever rub Trichlor pucks on vinyl).

Does the fact that it is a salt water pool have an effect on the chemistry of this operation?

No, not for the ascorbic acid treatment, but for the metal sequestrants some work better in salty conditions than others. Jack's Magic has a range of different products -- the HEDP ones are best, but they have some they say work better in higher salt levels (e.g. The Magenta Stuff ).

I used Leslie Stain Remover (two containers to be exact) in my 30,000+ gallon pool. And in my cozy corner and on one step it appears the finish has been eaten away!!! Help!!! Is this normal, the cozy corner didn't really have any stains on it now it looks like it does!


Thanks

Thanks chem geek
My pool is 15,000gal so I ordered the 5lb bag. $30 is not too bad if it works :wink:
So I guess I add about a pound at first and see how things go.
