And, lemme guess, they had something to sell you to fix that?

Please, please post your K2005 test results . . . and please consider purchasing a K1515 DPD-FAS add-on for your K2005. (link to PoolSolutions page with links to items on Amazon, in my sig below)

Meanwhile, keep your chlorine high.

(By the way, I deleted your other posts asking the same question. Please ask once, in one place. It makes forums really really messy when people start asking their question in multiple places.)
