Question about metal stains

[michael3]

Also heard that if its organic you can try and rub a trichlor puck/tablet on it, so I'm gonna try that to. I'm also hooked on the DE powder lol, I add alittle after each backwash just to help keep the water really clean, it seems to work. Before I put the valve in between the pump and filter I never had to backwash because the pump just forced the water thru the sand without filtering it, now it's throttled back and my pressure actually rises and requires backwashes lol. Just another example of the awesome advice from the pool forum

Steve, Well the vitamin c was working but it just doesnt go far enough, I would say I probably have stains on over 75% of my liner,so buying bottles of vitamin c will end of costing more than buying the ascorbic acid. Did you get your liner patched? Hope things improve for ya. We spent about 3 hrs in the pool for the first time today.
