In 2011 I drianed 75% of the old pool and refilled from the same well with no issues. Soooo my guess would be I don't have a metal problem.

I have a sand filter with 1.5 hp pump Haywood.

Been using the BBB method with no issues in the past.

Some duumbass cut a tree down on the old pool...that would be me.

I am using the Taylor kit that the site recomends.
