Losing chlorine

[Watermom]

So even after draining half, you are still at CYA over 100? Wow! You will have to either do one of two things:
-- Do another drain and refill of 1/2 to 2/3 water again to try and drop cya further or
-- Run higher than normal chlorine levels to compensate for the high cya. That would mean that you would have to keep your cl between 8-15 ALL the time and when you need to shock, you'll have to take it up to 25.

You need to get some bleach in there and bring your cl level up ASAP.

No more tabs or powder shock for your pool as they both have cya in them and yours is WAY high. Stick with bleach.

How does the water look?

The water looks great. My cl and fr cl are both at the max on the scale in the taylor kit. I must be using the kit wrong since I only see a 5 at the top of the "cl" and "10" under the bromine column.. You mention keeping the levels higher, how do I do this with the kit? How do I differentiate the higher numbers?
