I used borax last year and the pool has developed some nasty stains, I never had any staining before
It almost looks like rust brown/yellow staining
I read about the ascorbic acid treatment
Will this work here?
I also found citric acid in quantity which I used to use on stains on dishwashers when I used to service them
Which is more effective, I see citric acid is much less expensive?
I have a 16x32 vinyl pool approx 22k gallons running a de filter
it is a salt pool now and I am using a intellichlor chlorinator, the stains were before I added the pool salt
I see I have to get the chlorine level as low as possible
what dosage of ascorbic or citric acid should I use
thanks for the help...
