This year I installed a SWG with my Game SandPro 35D sand filter. My pool is approximately 2222 gallons.
I noticed a while ago that salt seemed to be building up on the plates of the SWG. For the past week I have been getting "low pump flow" notifications, and the system shuts down.
I have checked the filter/pump system, and all seems fine. I can feel the water coming back into the pool, and it seems to be about the same as it has always been, though sometimes I can see air bubbles from the water moving turbulently over the plates (when that occurs, it works fine). Other times the water is moving, as evidenced by water continuing to come back into the pool, but there are no bubbles (then the system shuts down).
I have had to begin adding chlorine and shock the pool as I could not get the SWG to run long enough to keep the pool clear. Prior to the flow issues, the pool was beautifully clear.
I wonder if the salt build up on the SWG prevents it from being able to "feel" the water flowing over the plates???
I have read a bit on other threads. The "high salt" indicator was on when I first started up the pool, but I drained some water and added fresh, and since the all seems to be fine. However, I wonder if the salt levels are too high and that is why there is build up on the plates. One hose connection also has a bit of salt build up crusted on the outside.
I saw some discussion of ppm of salt in the water, but I have no idea of how I would test for that.
I love swimming and my pool, but I dislike the abundance of chemicals typical in pool use and would love to find a way to maintain the pool with the minimum levels of added chemicals. It is not a high use pool. Generally, it is used about an hour a day for lap swimming, by me, only.
