About three weeks ago I posted that I had some white, chalky stains on the sides and bottom of my fiberglass pool. The stains are my fault; I hadn’t yet begun the TFP maintenance regimen. Using test strips (I know….bad, bad, bad!) the pool’s TA indication showed to be way low. So…based upon the directions and required amount of product recommended on the box, I proceeded to dump a good sized box of “Alkalinity Up” into the pool. The stains showed up within 30 minutes or so (don't know what caused them) and all attempts to brush them off have failed. Now…I found a product at Leslie’s called “Leslie’s Ultimate Scale and Stain Remover”. The product info states that it’s a non-irritant to swimmers (not an issue in this weather) but I’m wondering if this stuff will throw my other chemicals off AND will this product really work.
Any information would be greatly appreciated. Thank you.
