Stains in Fiberglass pool
I get brown stains in my fiberglass pool all the time. I can effectively remove them with oxalic acid, but it always turns the water cloudy for about 3 days. Jack's Magic Blue Stuff also works, but it costs me a fortune at over $20 a bottle. I heard somewhere about using ascorbic acid. Where can I get it in bulk? Is it expensive? Will it turn the water cloudy? Will it get the stain out?
Heres a link for Ascorbic acid

I have a 35,000 gal fiberglass pool and it stains all the time. Dont have a heater, and no iron pipes. It takes about a pound to a pound and a half of ascorbic acid to make the pool beautiful again. This is the cheapest I've found for it. $45.00 for 5 lbs. and if you buy over $100.00 at a time its free shipping. Heres a pic of my fiberglass pool.
