Green pool, advice from local pool store?

You can add a Taylor K-1515 FAS-DPD kit to your K-2005 and get accurate chlorine measurements at high chlorine levels. You'll have every thing in the K-2006 plus the color match DPD chlorine test.

His kit is a k-1005, NOT A k-2005. It is a different and less expensive Taylor kit. While it is a serviceable DPD test kit it is not as good as a K-2005 or K-2006.

20 ppm is fine, if you have a concrete pool.

Ben, his first post said 34k gallon gunite!
