Hi Mike;

1. Taylor "Complete" as in, K-2005 with DPD color match? If so, go to the testkit info page, and order a K-1515 DPD-FAS supplement. With your pool's high CYA, you will absolutely need it.

2. Collect a new water sample. In a glass mixing cup, add 1/4 cup of pool water, and then 1/4 cup tap water. Mix. Fill your CYA sample bottle with this mix to the first line. Add CYA reagent to the 2nd line. Do your CYA test again. Multiple result by 2. Yes, it's VERY possible you have a CYA level more than 100ppm.

3. Buy 4 gallons of plain 6% household bleach. Mix 1 with 3 gallons water (you don't have to mix it all at once -- if you spill this mix on your clothes, you'll need a new set of clothes!). Pour the mixture into the pool from at least 4 different locations.

4. Figure out how much it would cost to drain and refill with fresh water.

5. Post the CYA test result, and the estimated refill cost.
