Hi. Has the pool store checked for iron and copper in the water? Green water that doesn't respond to high levels of chlorine if it's heavily laden with copper. But unless it is:

Here's what I would do, but it's up to you. Drain off 1/2 of your water and refill. Test everything with your K-2006 (use the 10ml or 5ml test for chlorine, not 25ml). If your CYA is still over 100, add sufficient bleach or LC to bring FC up to a minimum of 25ppm. In YOUR pool, if you go higher, even a lot higher--like double to 50 or 60ppm of chlorine it won't hurt the pool. It's not vinyl, so it's resistant.

If your CYA is STILL up like 150 to 200, I'd again drain off half and refill. Get that CYA down to manageable levels.
