Ok, so we went of town for a week and had the chemicals all in check. When we got back the SWG was reading low and the cell isn't on, flow is green and all the percentages are flashing. I'm quite confused on this. Now that I'm researching I'm finding that I should have the swg turned off fully until I get all chemicals in check, is that something ya'll agree on?? Also I am reading about TDS. Should I be testing for dissolved solids? I have never even heard of that before. Thoughts?? I'm vacuuming up the dirt for the next couple of hours and plan on testing. Also, can you use an alternative to Cyanuric Acid to raise it? Is there a liquid form?? Thanks in advance. Also, once you get your numbers in check what typically do you keep your SWG on and also VSP? I live in Arkansas where it gets pretty hot in the summer. The VSP and SWG are brand new to us. Everyone says it's easy, but I am difficulties figuring it all out.
