    Chlorine / CYA Chart

    Any particular reason the chart for "SWG Pools" CYA range is limited to 60-90? I understand that this is the desired range, but I am in the midst of a new pool start-up and bringing CYA incrementally. Am I to assume FC = 4 is good for any level of CYA < 60?

    That would be a good assumption. If you go with that you'll be in good shape.

    The Pool Calculator can calculate numbers for any CYA level. Entry your current CYA level in the Now column and read out the recommended levels in the blue Suggested FC Level section towards the bottom.
