We built our pool this past fall and it was finished in October. We had the system setup with a Jandy Aqualink Powercenter with the Aquapure 1400 system built into the power center. We never set up the SWG because we were told that in the winter the salt would not covert into chlorine if it was too cold. Our pool has been sitting at 47 degrees until yesterday when we finally put the solar blanket on it. We didn't do it before because we have dogs and wanted to make sure they were going to try to walk on it. Now after just one day, the temp is up to 50 degrees. I found out that it needs to be 50 or the system will not turn on automatically. Apparently it can still be used 24 hrs at a time if put into boost mode. Anyways, I am thinking that by tomorrow it should easily be higher than 51 degrees, so I have been wanting to get this thing up and going. Our pool is 12,500 according to the city water meter when we filled it. According to Jandy's salt chart it says that we need 300 lbs of salt for 12,000 gal. Am I reading this right? Just seems like alot of salt. I am new to this and would hate to put way too much salt in. We built our own pool and just subcontracted out some of the stuff I couldn't do myself and all of the people we talked to said we could just go to the grocery store or lowes and buy water softener salt. Is this true as well? I am eager to get this going as I am tired of buying and storing the chlorine when I could just be using the salt like originally intended.
