After reading more on this forum and being confident I did not need to pay someone else to maintain my pool, I installed a Nano Digital SWG and converted it over. I've run into one issue. My FC does not seem to be coming down from the crazy high level that the service company was keeping it at. After diluting pool water 2 to 1 with Distilled Water, I got a FC of 33, and that's after two weeks since they did their "weekly shock". I have turned down the SWG to 30%, but with a 10k pool, and SWG rated at 22k, I expect something else is keeping the FC so high. Any ideas? The CYA is also quite high at 120, and I've considered draining and refilling some to bring it down. Is that suggested?
