Stain on fiberglass pool

Postby lonnie » Sun 20 Sep, 2009 11:37

I have a yellowish/brownish stain on my fiber glass pool below the water level. I tried rubbing it with a Vitamin C tablet and it takes it right off, I can actually write with the tablet. However, I bought some of the Stain Free stuff (ascorbic acid) and put it in the pool with not effect. Any ideas on how I can get this pool cleaned before I close it for the year???? Any help appreciated!

If it comes off with vitamin c it is probably a metallic stain. Add a metal sequstering agent.
