Greetings! I have an in-ground, 16 year old, 30K gallon pool with Pentair Easy-Touch 4 panel, Superflow VS pump, FNS-36 Filter and MasterTemp natural gas heater. I do not have a spa nor salt system associated with the pool. The Easy-Touch and Superflow VS pump are new. I'm now trying to de-bug my system and better understand operation.
