I am learning about pool maintenance and keep having high levels across the top 5 so looking to see best practices for balance. Live in Arizona and am chicken for cold water. Looking to see how to extend those amazing 84º water temps. Can you believe it gets up to 92º in my pool in summer! I love it. Also looking to see how I can close the pool without a real cover. lots of dust/dirt and leaves blow into the pool all year round. Freeform pool shape and rock features make a cover a bit difficult
