I'd throw a submersible pump in there and let it throttle for a few hours while moving it once in a while to get a good mix. Then c heck again.
No it was 35 for an end result of 70 total. If it were still 140 I probably would’ve just set the pool on fireYou got a 70 with the diluted test? Meaning that your CYA is still 140? Or diluted was 35 meaning your CYA is 70. Can you clarify?
If you got 70 on the diluted, for a total CYA of 140, then I would run the pump and maybe jump in the pool and mix the water around...a bunch, then retest. It may be that the water is stratified and not mixed yet and you grabbed a sample from the old, unmixed water.
If you got 35 on the diluted, meaning your CYA is truly 70, that is likely because you didn't actually replace 2/3s, you only replaced 1/2. You have a choice...either replace about 20% or SLAM at 70. Given the size of the pool, I'd replace some more water...
I’m about to shove those pucks up a chlorox CEOs rear! What’s more frustrating is I used pucks for the first 2 summers without issue but have no idea what brand they were. They obviously didn’t have the amount of stabilizer in them.I would also guess your problem is exacerbated by the use of COPPER containing pucks. That Clorox XtraBlue contains copper.
We NEVER recommend copper products in a pool.
Your draining and refilling will assist in lowering that copper level.
Liquid Chlorine is the best product for sanitation as it doesn't contain unwanted CYA, Calcium...or copper

Give me a buzz before you do that, I'd love to witness thatI’m about to shove those pucks up a chlorox CEOs rear!

Add 30ppm of Dry Chlorine Stabilizer using the sock method. No need to be gun shy. This will help your chlorine usage, and not be a deterrent to Slam or anything else. Should help you through close.The dot never goes away even filled all the way to the top.
Don’t stop with slam unless you’re also crystal clear with no recurrent algae (dead or alive).I’m done!!!! Yayyyyy! Pool is beautiful blue and passed the overnight loss test. Now I need help maintaining. Since I don’t have an automatic chlorinator and I can’t use pucks anymore I have to get the chlorine to hold out longer. I’m burning through a gallon a day and I can’t afford to keep that up much longer. I’m assuming I now need to increase the CYA but I’m a little gun shy now. I’m reporting it at 30 but it’s less than that. The dot never goes away even filled all the way to the top.
This was my reading tonight. After I added a gallon of chlorine and put the solar cover back on to hopefully help it from dropping too much until I can get back to it next which won’t be until Thursday morning.
