First of all, I should say I'm a total newbie to the SWG system, and we got one recently installed for our pool (no more chlorine).
It was installed by the contractors who resurfaced our pool. Once it was started up, the number was 2800.
Then the next day, it fell all the way down to 1400, and "check cell" light was on.
We have a bag of salt ready to be put in to bring the level up, but we are concerned as to why the number fell down all of sudden, we think this might be misreported by the system, due potentially to other issues we are having at the moment: Lots of peebletec "debris" on bottom of pool that needs to be removed. The resurfacing team removed a lot of it the other day, but some still remains. Our cartridge filter also needs to be replaced (it is "full", and is causing flow issues at the moment). We have new filter cartridge on the way to replace this old filter. Also considering collecting loose "peebletec" stuff via a new "canister" somewhere in middle of our vacuum hose (one-time thing) to protect our new cartridge filter as much as possible.
Could flow issues be causing "check cell" light and low salt numbers to surface, or is this more likely something else wrong with the salt system?
Thanks in advance.
