Any thoughts on running the pump while filling the pool? See pic above.

Why not? It'll keep bleach mixed and might even filter out some crud. All that aeration will definitely drive pH up, though.Any thoughts on running the pump while filling the pool? See pic above.

Really?! Evaporation doesn't diminish CYA?Welcome to TFP!!
My first suggestion is to stop going to the pool store. Their only response it to sell you something or give bad advice (they have done bot to you by the way).
I will tell you, it didn't get like this overnight and it will take time to clear. June 11 may be pushing it but may be possible. We can teach you how to get it sparkling and keep it that was for a lot less money than the pool store.
Not much credence is given to pool store testing around here. While you would think that a "professional" would be the best, unfortunately in most cases it is quite the opposite. Between employees who blindly trust the word of chemical sales representatives and high school kids working in the pool store for the summer you end up with poor results from their testing. But, what can you do?? We base our pool care system on accurate testing and only adding what the pool needs, when it needs it. To do that you need your own accurate test kit. Order a TF100 and at least include the XL option today. That will give you what you need while you are clearing the pool, and probably enough reagents for a couple of years normal use.
While you wait for it to get delivered, you have a homework reading assignment. Start with ABCs of Water Chemistry and Turning Your Green Swamp Back into a Sparkling Oasis
You have a big pool, so with the pump running I want you to add 1 bottle (121oz, 8.25%) concentrated bleach in the morning and at night until the test kit comes in.
The tarp method really isn't necessary as it doesn't work that well. For now a 50% drain/refill will get your CYA in the 70-80 range which is survivable.
Replacing water through evaporation doesn't reduce CYA. When water evaporated, it leaves the CYA behind in the pool water.
If you don't order the test kit today, June 11th by our methods is probably not in the cards.
So the refill will eventually dilute and lower CYA?Correct. Evaporation does not lower CYA just like it does not lower salt. Only the H2O evaporates.
Jason already answered, but yes. As the water evaporates all of the dissolved materials in solution remain in the water. So, if you could test to that level of specificity, the CYA actually rises as water evaporates because there is the same amount of CYA in less water. Add water back and the CYA level goes back to where it was.Really?! Evaporation doesn't diminish CYA?
I do. Thanks.Jason already answered, but yes. As the water evaporates all of the dissolved materials in solution remain in the water.

CYA only goes down when you remove the solution in whole, meaning the water as well as the dissolved materials contained within. Kids splashing water out of the pool, you CYA goes with it. Dog jumps in and leaves wet, he takes CYA with him. Backwash the sand filter, CYa goes down.
You get the picture......
Good - got the chemicals - bleaching a couple of gallons a day along with sweeping towards the drain in the deep end and awaiting the test kit to figure out what I need to do. Tuesday will be go time! Thanks! Might need more borax.Dsteadman: Staying on track with YOU... Still.

How is it going?
Thanks. I'll keep diluting. It's a slow process but it's working. Hopefully, by end of summer I can get it in range. Meanwhile, cornering the market on bleach!The only thing that evaporates is water, everything else stays behind, calcium, salt, borates, CYA.
