bbb,
Welcome to TFP.. A great place to be!!!
You will love a SWG pool. It is normal not to add salt for about 30 days. Obviously, without the salt the SWG will not work, and in fact should be turned off. You definitely need to have your pump running for 6 to 8 hours a day, but with a VS pump, running it 24/7, at a low RPM, will not hurt anything.
The two main readings you want to keep in check are your FC (Chlorine) and your pH level. We do things a little differently than most pool builders, so I suggest you do two thing..
First... read our "Pool School" using the link at the top of this page.
Second... After reading pool school you will understand the importance of having an accurate way to test and report your pool's water/chemical balance. I have a recommend the TF-100 as the best test kit around.
What test kit are you currently using?
The whole TFP process for taking care of your pool, is giving you the ability to test your pool, and then using "Pool Math" (Link above) and adding just what you need to keep your water safe and clear. No going to the pool store ever again.
When you are ready, please post the following test results:
FC
CC
pH
TA
CH
CYA
Got questions?? I'm sure you will, and there are a ton of people here to answer them.
Thanks,
Jim R.
