Mmm, thank again for the update on improper testing, but just as a general question, well water is very high in many different metals, right? In general would a stain and scale remover help (weather I use it next year as I fill the pool) or could it be helpful now, late in the season. I know other pool insight,apps, sites or pool professional stores are against every thing tfp stands for.. but my chlorox app tells me to add stain and scale for my water hardness...? That app took into effect that I fill with Well water ... And here no one even cares what my water source is.. "drain and refill"... If my water source is the the cause of the high metals, why would I drain and refill???
