Thanks for the response! I don't follow you though.
Intex is recommending a lower CYA. It sounds like you might be asserting the industry wants you to have a higher CYA to sell you more chlorine?
Sorry if this has been asked before...just noticed Intex recommends 20-ppm for CYA for Model 7110 and 8110 Salwater System. Wonder why? TFP recommends 70-80 right?
