Taylor makes a very nice salt testing kit for around 15-20 bucks as I recall. You absolutely must test your level. Until you do, you won't have a certified answer. Aslo, how did you add the salt? Did you disolve it in a bucket first, or did you just dump it in the pool?
Your SWG is only "running" for as long as you program it to. Mine runs for about an hour a day. Read your instruction manual and you will see you need to keep the power on it 24/7 so it retains it's memory. So you program it to come on at 8am everyday, and every day at 8am it will come on, do it's thing, then turn off ALTHOUGH the led lights may be illuminated and I believe the "sleep" indicator light will be on. Run the pump as much as you want.....
