Hey gang, happy spring!

So, how do I do this? There's a section header regarding this topic in PoolDoc's "Before filling your pool" sticky, but no further info (section 7c.) I have a 3800 gal Intex with copper that I need to get rid of. In the past I've used BioGuard's PoolMagnet and then filtered it out (with a filter aid in sand filter.) But I'd like to try this chlorine + pH approach so as to avoid buying more pool store chemicals. Thanks!
