I am in the process of switching my pool over to salt water. I am working on getting all of my levels to where they need to be before we start up the generator. My salt level is at 3400 which is right where it needs to be as per my generators instructions. My free chlorine level went way down over these past couple of days and I think I may need to go ahead and shock before we make the switch over. I plan on using liquid chlorine to shock with. My question is do I shock per the standards of a saltwater generated pool at a CYA of 70 (thats where i am w/ CYA)? My other question is why on a freshwater pool does the free chlorine go up as the CYA goes up but when I look at the salt water CYA chart the free chlorine level is down for a higher CYA? Example freshwater pool CYA of 50 calls for free chlorine levels to be between 6 to 8… Salt water generated pools with the CYA of 70 to 80 call for 3 to 6 ppm a free chlorine? Just curious.
Switching to SWG...Have question...

If you don't have algae you don't need to shock/slam.
All you need to do is bring your FC up to the desired level with liquid chlorine and then let the SWG take over maintaining that level.
Test daily to see if your device is set up right- When you need more or less chlorine you either change the number of hours on your pump or you increase/decrease the percentage on the SWG. It will take some tweaking at first to find your happy place.

Ok- it doesn’t appear to have algae...so I’ll just get the levels up and move from there. so as far as my FC level, with my CYA currently at 70 and my salt level where it needs to be (3400)- I’m assuming that I am trying to get my free chlorine up to the standard for a saltwater pool although I haven’t officially started my generator? Sorry if that’s a dumb blonde question I just want to make sure that I’m doing this right before we get started.
B,
Chlorine generators produce chlorine very slowly.. They are designed to "maintain" an FC level, not to generate a lot of chlorine all at once. This is why you should add liquid chlorine/bleach to get your FC to about where you want, and then turn the job over to the SWCG...
An IC40 is a little on the small size for your pool.. We always recommend using a cell rated for at least 2 x the volume of your pool...
Just as a heads up... most pools use 2 to 4 ppm of FC per day... So if your pool uses the average of 3 ppm per day then you will have to run your pump for 13 hours a day and set your cell for 100% output to generate 3 ppm of chlorine per day...
I suggest you start high and work your way down...
Thanks for posting...

There are a few theories on this but as Jim pointed out the SWG is maintaining a constant level of chlorine so you don’t get highs and lows you may get with just chlorine. Also since a SWG usually runs for a longer period of time you are getting more turn over and a steady stream of chlorine is be produced. The SWG is also producing in a confined space so at that point the water is “super chlorinated” so it’s believed to help kill off bacteria before it gets a chance to reproduce.
So your chlorine level can be lower
Jim,
Thanks for the reply. I need to update my signature. We went ahead and upgraded to the RJ 60.
