Like the title says, I am wanting to add a swg to my pool and can't decide which to go with. My pool is ~22k gallons and the gets full Texas sun. It seems that the Heyward is the most liked system but they only have a 40k gallon system and I think I would be better off with a system bigger than that. Does anyone have recommendation on which would be the best (and still economical) system for me to go with?
