Last fall I purchased a Bullfrog X7 spa which came with the Frog ease SmartChlor cartridge system. I’m not convinced that this is the best system to use and thinking of changing Any suggestions? I’m a spa novice so I’d appreciate if your answers are “dummied” down Where do I start? I just drained, cleaned, and filled my spa yesterday and haven’t added anything in it yet (brought it to 100°). Thanks In advance for the advice!
