80,
Just to be sure we are all on the same page, a saltwater pool is a chlorine pool, so basically the testing is still the same. The only real difference is that you now need to know the salt level in the pool.. The Salt Water Chlorine Generator (SWCG) just uses the saltwater and electricity to create the chlorine your pool will need each day. So, instead of manually adding Liquid Chlorine, the cell does it for you...
You also need to understand that the cell will not work once the water temperature gets below about 55 degrees... In the winter, assuming you do not normally close your pool, you will still need to manually add Liquid Chlorine, but you won't need much in the winter months..
Once you get used to how your pool operates with a SWCG, it is possible to only test once week. I run my FC a little on the high side so that I don't have to worry about it going too low.
If I built another 100 pools they would all be saltwater pools.. It makes pool care almost effortless. Don't get me wrong, you still have to test and ensure your water stays balanced, but the SWCG makes it very easy to do.
Just make sure that any cell that you buy is rated for at least 2 x the volume of your pool.. This is important because cells are rated when running at 100% and 24/7..
Thanks,
