Looking for recommendation on the lowest power consumption and easiest control option for 8,000 gallon salt water pool and Spa, Spa has one valve for water feature that I'd like to be able to turn on and off. Was thinking a Pentair Intel flow one and a half horsepower pump and three micro bright lights plus control for saltwater generator and heat pump. Trying to avoid the ultra-expensive control box is hoping there's a simple option that works well together
