My neighbors and I follow the TFP
method of closing our in ground pools. The 2 long time pool owners swear to adding a flocculant named Drop Off after you finish adding the Poly 60. Both testify how when they open in spring, they remove their cover. vacuum the bottom of the pool to remove settled algae and degraded containment
to waste, shock with bleach, run the pump for 24 hours, test and balance and open in less than 2 days! My question is, "ANY" downside to adding a flocculant when closing? Thank You!
