Last week I cleaned my intex Krystal clear Swg for the first time as there was a lot of salt build up. I used white vinegar and an old toothbrush to get the majority off and then let it soak in vinegar for a few hours. After that I put it back together and ran the pump for 24 hours before turning the Swg on again. Well each time I try to turn it on now it reports high salt error. It's been 4 or 5 days, and two separate salt tests result in 2800 ppm, and after dilution, 2600ppm. So, is my Swg knackered?
