Hi, my husband and I have just erected our first intex AGP, size 32' x16'x52", so we are new to this... Water testing we are familiar with as we have a hot tub. We have an Intex sand filter/pump SWG and a heat exchanger attached to the pool. It has now been running for about a week.
The Intex information said to add 165k salt, we have.
Right from the start the SWG alternated from 'working' to fault code '91', low salt. We turn it off, turn it back on and it goes to 'working', after 1 - 2 hours, it starts beeping code '91' again.
We believe that having added the recommended amount we shouldn't add more? Is this right?
We have tested the water with Aquachek white (salt) test strips. On the first test this morning it read about 3000 ppm, we did another and it kept rising?
Also checked other chemical levels with Insta 3 way/5 way test strips. They are not showing any chlorine, is this right? But all other levels are ok.
The water temp started off at 15 deg,and is slowing rising (now 18)but would that have any effect?
Should we add chlorine to be on the safe side? What else can/should we do to make sure SWG is working correctly? Any help greatly appreciated.
