I recently converted to the Saltron Mini salt water chlorine generator for my spa. It is working perfectly. Now, with my pool I also have a SWCG, and I never shock the pool. Never. The pool is perfect. According to the instructions that came with my Aquapure 1400, they say that shocking is likely not needed since the chlorine level inside the generator is very high, and shocks the water as it comes through it. That has been my experience with the pool. For those of you using a SWCG in your spa, do you find the same? My spa seems perfect, the FC level is 4, and there are no CC's. Can I get away without the weekly shock of liquid chlorine?
