I am totally confused trying to purchase a maintenance system for high temperatures in South Texas. I was told a Salt Water system wouldn't be efficient in higher than 90 degree weather by a 'pool dealer'. He told me about the Baquacil 3 step program. Then i went on utube and saw the BioGuard SoftSwim. Doughboy has a ozone system and a mineral system, but I've read bad things about both. I just need to get advise on what is maintenance "easy" and will work with high Texas temps. Any advise helps!
