WOW, JUST WOW!!! From the original pics, it was hard to imagine how much gunk was in there AND how deep that deep end was! That was/is an undertaking of immense proportions and you and your "crew" should be more than proud of your accomplishment!
Great call on the suggestion to monitor your meter on refill to more accurately calculate the total volume of pool. The complex shape is so hard to get right. As well, in a reversal to my original thoughts, now that you have drained to the level you have, fears of floating are greatly diminished but you still do not want to tempt fate...your timing was good because we did not have a rainy spring. I still would not worry to get every last drop out, but rather put the pump in the lowest end while you are finishing up the power washing as you will be sucking the dirtiest water out while replacing with the clean from the power washer. Get it clear enough in that lowest "bowl" to verify the bottom drain grate is not busted up and any remaining solids are gone and start your refill. In such a large pool, that lowest part not being calculated on the meter during refill will be a rounding error...probably less than 500 gallons I imagine.
I agree not to pour bleach down sides, since you power washed sufficiently, the bleach adds nothing to cleaning the walls and could be problematic. In the full sun, most of it's effectiveness will quickly bake away. Rather save it for full effectiveness when you get it full and circulating. Instead, while using trichlor tabs for the long haul in an established pool is not a part of the recommended BBB methods, I would suggest getting a medium bucket and a couple of floaters and fill them up and throw them in for a while--maybe once you get to the halfway full point. This will serve the purpose of getting a constant source of chlorine into the water and begin adding some cya to the water to stabilize the chlorine you will be adding for a while. You will still need to invest in cya and get that to a 30ppm level and eventually to 40 or 50 as quickly as possible. It is hot and sunny as you well know and you will minimize your chlorine expense by stabilizing it and not having it bake away within a few hours of sunrise each day. With all of your hard work, you don't want the water going green before you have a chance to get it balanced.
I don't have one but am considering adding, your pool might be good candidate for a salt chlorinator. A lot of water to keep chlorinated in hot and bright Texas sun. Just a random thought...others will probably will have better opinions.
I do agree on the resale aspect. I don't think looking perfect matters as much as working perfect. New tile and plaster in that big a pool can probably be had in our market for between $8-12k. But a pool in a house for sale adds very little if any to value. What it serves is to divide your market. There are those that will never consider a house with a pool. Then there are those that will only want a house with a pool. The rest will depend on how the overall property meets their needs and price point and the pool will be seen as either an added bonus or something they are willing to take on because all other boxes get checked for them. So if you are short term, I would not worry with a remodel...just makes sure it works properly and isn't leaking at time to sell, enjoy it while you live there,and you will maximize value.
But yeah, I am amazed and utterly impressed. I am a pretty self reliant and do what I can rather than paying someone else, but I am not sure I wouldn't have thrown my hands up over the past couple of days and called in some kind of cavalry!!! And the gunk you dumped in the back corner of the yard, in time spread it throughout your flower beds or garden and your flowers or veges will be the envy of the neighborhood!!! LOL
