OK. You've got a K2006, so we can start testing.

We've got a baseline of
FC: 20
CC: 0
pH: 7.4
TA: 110
CH: 120
CYA: 50
Here's what I want you to do:

1. If your pump is not running 24/7, set it to do so.

2. This evening, add 1 full gallon of PLAIN 6% bleach to your pool. Test the FC level (10 ml sample) BEFORE, and 1 hour AFTER you add the bleach.

3. Tomorrow AM, before 8 am, test the FC level again (10 ml sample) Then, if the chlorine level is below 20 ppm, add another gallon. Post your results.

4. Make a list of EVERYTHING you've added to the pool, from the time just before it turned green, till now. Be as complete and accurate as possible. If you don't know quantities, include brands and products without quantities. Post that info. Include approximate dates.

5. Tomorrow PM, do another complete set of tests (FC, CC, pH, TA, CH, CYA) and post the results. Then add another gallon of bleach.
