You can order the K2006 from a lot of places, including Taylor Technology (for MSRP), it's just Amato via the link helps support the forum.
Alternatively you can go to Leslies On-Line and order their Chlorine FAS-DPD Service Test Kit, which is a re-badged K2006, at the K2006 MSRP.

If your pool is 10% out of level, that means it's almost 5" out of level...failure and collapse are likely if it's that much.
