Salt water is actually a little cheaper to maintain, the salt is cheaper than chlorine, but both are only a minor expense. Solar is another cost saver but no matter what filtration or heating method, the electricity is where you will get stung. Water has to move, pumps have to run about 4 hours in winter and 6 or 8 in summer, it’s like running your air conditioner every day. You live in Riverside county and SCE has higher rates than SDG&E, plus the way the bill works, the added electricity will all be at the highest over baseline rate, and last I checked, electricity rates aren’t going down. Get a friend with a pool who likes to entertain, it’s just like a boat, the best one is someone else’s.
