New to pool ownership.
Pool seller suggested using tabs in free floating delivery system - PPM never gets above 10.
Put the tabs into the skimmer may cause damage to the skimmer - PPM gets to 15 PPM.
Friend uses shock every night and uses pool the next day
Brother uses EZ Pool product plus granular chlorine.
There seems to be many ways to use chemicals and hundreds of choices. What is the best practice?
