I’ve tried everything possible to lower my combined and nothing worked. After talking to a bunch of PB, water testing, etc only way was a to drain it. Obviously I’m not doing a full drain and risking damage. I lowered the pool to an inch below the skimmers and closed the valves. I’m am draining from the main drains in the deep end on the bottom of the wall threw a waste pipe after the pump in between the cartridge filter. On the opposite end I have two hoses going into the pool. I have the valve draining the pool at the exact same rate as the water going in. 17.6k gallon pool I’m looking around 35 hours for a full swap then I’ll top back off? Sound about right??? When I’m don’t I will vacuum the bottom and clean the filter. I hope this gets rid of the CC!!! What should be my first step getting the PH correct then adding chlorine then the salt ?

What is the pH and TA of your fill water?
I would get some stabilizer dissolving in a sock and add 5 ppm of liquid chlorine as soon as it is filled.
Then make pH adjustments 30 minutes after adding the liquid chlorine.
Toss in the salt while waiting to adjust the pH.

What test kit are you using that you get a TA of 111?
I asked what the pH and TA of your fill water is, not your pool water.

Just a note - it's safer to use a submersible pump to remove water than your pool pump, just in case something happens and it loses prime and runs dry. They're not too expensive from places like Harbor Freight, or you can rent them from places like Home Depot.
The methods used here might have been able to correct the water without exchanging it, but we would need to know what the full water chemistry is, and we only trust results provided by people who are doing their own testing with a dropper-style (FAS-DPD) kit, like the Taylor K-2006c or the TF-100 test. It could be that if your CYA is sky-high you need to exchange water anyhow, so it's not like it's for sure a waste to change out the water, but if the methodology this site touts is used, draining a pool is almost never needed.

Thanks CYA was 73 before this happened and FC 2.5. I never removed the Autocover for a month and the water temp was 75-84. I realize now that was a mistake and at some point the chlorine got taken over and all the breakdown is gases never escaped and it was a never ending cycleJust a note - it's safer to use a submersible pump to remove water than your pool pump, just in case something happens and it loses prime and runs dry.

OK. I'm assuming you're not using a home test kit, and are relying on the pool store's numbers?
We do things really differently from pool stores here - it's a lot more scientific, and a lot more control over what goes into your pool and the chemical state of it. While we can offer some advice on things like draining/exchanging water in a pool, we would really recommend you get your own reliable test kit (FAS-DPD style, like the Taylor K-2006c or TF-100) and take control of your own testing. Then you don't have to worry about ever needing to drain your pool again.

OK - then you can't say 73, because we can't read between lines on the Taylor CYA test. It's logarithmic. You'd round up to 80.
How is the exchange going? If I were you I would hold off and give us a water test. Maybe you can stop it, just fill up, and we can assist from there.
