I have a 20000 fiberglass ig pool. I am in the progress of doing the acid test. Last night I put in 1 lb and put on recirculate, about an hour latter I put another lb in because it did not get all the stains. I left it on recirculate all night and this morning it looks good but streaky on the walls, so I put my last lb in and kept on recirc.
What should I expect form this treatment, I mean the spots where the stains where lifted, it looks brand new, but on the other hand when is too much ascorbic acid, would it do any damage to pool equip.?
Should I add one more lb if it doesn't look much better? One last thing, do I wait til I am done adding the acid then put the sequest. agent in.
