Hello, I recently purchased the pure line salt system for my 20x40 pool. I also purchased a pentair 342001 variable speed pump that has a built in programmable timer. I understand that the salt system should not be on unless the pump is, if the pump has its own timer what is your recommendation to ensure that the pump and salt system are in sync with each other? Is the best option to have an external timer for the salt system and make sure that the clocks align with the pump? Thank you for your help and support
