So it has been a couple weeks and pool seems to be going good. I still have not fixed that threaded fitting leak as I keep forgetting to pick up plumbers putty when I am near the stores (~30 min away). The gasket did fix the leak on my sand filter drain, sometimes at least. It may be normal but when I set it to backwash I still get water dripping from the bottom as well. During normal operation it is fine though. I have been working on getting my chems right but haven't been trying all to hard since they aren't all that out of whack.
So once I got my chlorine up is when I started looking at everything else
at that baseline
FC 4.6 CC 0 PH 7.6 TA 170 CH 110 CYA 140ish (rough based on diluted test) Salt 4200
So since my CYA was super high I worked on getting the Chlorine up while I spent time researching and all that.
Maintained about FC 8 for almost a week.
I then drained about 4-6 inches from the pool ( I don't have a sump pump yet) and refilled. This brought my numbers to:
FC 5.5 PH 7.8 TA 150 CYA ~100 Salt ~3600(I've ordered more reagent to try another diluted test)
Today I am at
FC 6.5 PH 7.6 TA 120 as I have been working on getting the TA down with muriatic acid. Playing around with Pool math it seems that FC should be OK in my current range if my CYA is actually at 100, but I know isn't advised. My FC has been hanging around 6.5 -7 for the last 5-6 days (since the refill). Right now I only run the pump about 4-5 hours a day with the SWG around 40%.
When I think about it it seems a bit overwhelming so I am trying to just focus on one part at a time, I already used a gallon of acid so I have to pick up another gallon or so this weekend to get the TA lower. I may also have to suck it up and buy a sump pump to drain water to get the CYA down but if I can avoid that I will.
Other than those concerns the pool has been great, I realize this winter I am going to have to severely trim back a nearby tree though.
I have slowly been working on grading out the area around the pool to avoid having to put up a fence but since i can swim motivation on that has been lacking.
I probably could have made the return line shorter before going underground if I swapped the flow switch and SWG but I wanted to keep the switch in a spot that could be disconnected in case of repairs without having to buy another union.
Budget wise is typical for me I had a written estimate of just over $1,775 and actual spent was around $1,850 plus some bits here and there I am sure I forgot to add in. My original budget had much less pvc included, I had the equipment pad right near the pool and the wife wanted it somewhere else which wound up being about 20' from the pool. I did not include equipment rental in the initial cost since I was hoping to do most of the de-sodding by hand

. Plus there were some odd and end things I didn't include like the pavers and clamps. I forgot to add in the cost of all the rustoleum I wound up using so that probably added another $50 or so. I think I shaved off pennies everywhere I could without affecting the final product.
As I figured the floor is bumpy as anything but I can live with that, If I had waited another week or two to get it perfectly smooth it still would probably not be up now and it has been in the 90's for the past week with no end in sight. Me and working in the heat do not mix anymore.
ETA: that little bit of green is a sinking leaf No algae at all and has been clear water since opening.
