Is your SWG tied into your pump run? How long do you normally run your pump to filter per day now? I'd start small (perhaps 10%) since your FC is currently high, then as it drops you can bump it up slowly to meet and maintain your FC needs. You're in a great situation now since your pool is still being protected from algae via the chlorine gas.

How long has the salt been in the water? You typically wait 24-48hrs after salt to make sure it is fully dissolved. After that, you can start it up at anytime. Problem is, your FC is so high it's going to take a while to get back to "normal".
I put 7 x 40# bags of salt Friday afternoon and late last night got a reading of 2900. I added one more bag about 3 hours ago and now show 3200. I realize that may change.
The SWG is on the same relay as the pump and is plumbed as the last piece of equipment in the water flow. It may be excessive but I run the pump for 13.5 hours a day in the summer. The first hour and a half is for the spa only and thanks to the Aqualink, the SWG won't run during that time.
Just to gloat, here are some before and after pictures. I had to do the PVC twice as the first time I developed a leak right after the flow indicator switch. The second time I was much more deliberate and went a little overboard with the purple primer and glue. Even got some on my shoes.
Before:
The previous owner had a SWG and the cell was a vertical mount. You can see that they patched the plumbing by using two 90 degree angles. I had to cut all that out.
After:
Because of the length of the cell, I had to extend the run out and around; I could not go straight to the return.
The Oxidizer on the wall was left from the previous owner and is not attached.
It's not very pretty but will look better once the PVC is painted and the wiring secure. Best part is that everything works and there are zero leaks.
So, back to my % question - any risk using the SWG only a small amount of the time? The logic behind my inquiry is in regard to the fact that high FC levels were needed (pre-SWG) due to the concentration of CYA. If I'm not running the SWG, aren't I at more risk for the green monster?
