Long story short, I have very high CH and TA and really have no way around it. I installed my Intex SWG last Thursday and by Sunday I had a low salt fault. I read on here to check the element and the plate(thank you TFP) and sure enough they were both caked in calcium. I unhooked the unit and started the cleaning process with vinegar as per the instructions, and after 2 hours there was still quite a bit of calcium everywhere. My wife suggested using some CLR, so I did. I mixed up a 4 to 1 mixture of vinegar to CLR and everything was spotless in 30 minutes. I hooked the unit back up and everything was working great again. Today is Wednesday and everything is caked up again in calcium. Does anyone see a problem with using a Vinegar CLR solution again and using this on a regular basis? Is there anyway to reduce CH without getting a different water source? Thanks in advance for input.
