The PB is plastering and filling pool this week and soon it will be my responsibility.
Pool has a Pentair 320 Chlorinator which takes 3" "Trichlor" tablets.
I have seen a number of quantities/prices on 3" tablets.
Are the 3" tablets sold at Sam's/Walmart acceptable for this?
PB told me to take water sample to local Pool Supply store which I will do but having had a pool at a previous house about 20 years ago I am somewhat leary of Pool Stores over selling.
Sorry to be asking what are probably dumb questions but PB is not going to be any help
