Tested pool and most stuff looked good but cya was over 80, so based on that I replaced about 4000 gallons of water. Now I heard or read u need to wait for about 7/10 days and test again. My question, will it be higher or lower right after replacing the water or after waiting time period. Just for heck of it I tested today (3days after) and had about 47 reading. Should I expect it to go up or down from there, thanks.

If you are diluting, you can test pretty much right away. The CYA is already dissolved and you are only adding water. If you are adding CYA.. it takes a while to dissolve into solution.

Test and find out. If the water exchange is done, it mixes in about 30 minutes for most pools
Don’t forget to always round up to the nearest ten. @mguzzy can take a swig of the vial and know it’s 33.72 with a few swishes, but the rest of us only need to know it’s 20/30/40 etc.
Then let's say it's 50, should I go lower or just stay. I've never had algae or really any problem except the cya got high for some unknow reason. Not really worried about me or pool just great granddaughter. Thanks
The April showers and the normal 4-5 ppm of monthly degradation should take care of the rest.
