Yes- my kit is Taylor k-2006. I've not done a CC because I wouldn't know what to do with that information. And I'm not sure what an overnight demand test is. Our CYA was extremely high last year (>200) I found that out when I couldn't hold chlorine and it led me here and I ordered my kit. When we opened the pool, our CYA was 0. I was worried about the ammonia? (waste products) caused from the algae if it ate all my CYA. However, the pool was partially drained and refilled right before closing last year. Before I added stabilizer, I verified the pool could hold 2 FC prior to adding stabilizer to make sure it wasn't full of waste products from eaten CYA. That was listed under one of the pool guides here.
