What is better a Salt Pool vs Chlorine Pool
Salt Water Chlorine Generator pools are a superior swim when compared to low cost chlorine, however only slightly better than good quality chlorine. The will cost the same over time, however salt pools tend to keep the pool water chemistry a little more balanced.
