Are the differing values due to water chemistry differences ( salt water vs. no salt ) or SWG ‘efficiency’?
After many years of SWG usage I am reluctant to replace my dead cell again, but I am having trouble converting back to ‘traditional’ methods and need advice on getting my numbers back into the sweet spot. I currently have 3100ppm salt level and haven’t decided on liquid or solid bleach or a combination. Right now I am really wondering were all my chlorine is going. Shocked my pool 6 days ago with liquid chlorine up to 14ppm FC, left a pool floater in there with two 3” trichlor tabs, and back today after a trip out of town were the following numbers ( water is clear but spots of green algae appearing on poorly circulated areas )….
20,000 gallons water temp 75F
.5 FC 0 CC
( pool refilled 1 month ago with city water, Chandler AZ )
