Hi - thanks for your time!

I thought I was treating one thing at a time. Metals. pH has to be low, can't add chlorine til levels are zero, so I'm trying to stave an additional issue of algae while I work the metals out. (and I do realize I'm not getting rid of the metals, just the water staining of the metals).

My fill water is from my well, which is riddled with iron. Had I known what a nightmare metals can be in a pool ahead of time, I never would have filled it from my well.

I've since purchased a pre filter to fit the hose (looks like a pillow in the shape of a bat) - but can I take confidence that it will remove all metals before getting to the pool?

Even if I partially empty/refill at this point, I'll still be dealing with metals for the life of the pool, no?

I can't completely empty because the liner could shrink. What are your thoughts on emptying to 1.5', refilling over the course of a few days with the prefilter, then emptying down 1.5 and refilling - think it might reduce my metals down to a point that I won't have to spend $140 in sequestrants? Makes some sense to me saying it - but what I don't know could fill a warehouse.
