The hydraulic cement is good for filling the holes in the deck where the slide  legs went through?

I've never seen or contemplated a contract for building a pool but it seems odd that the dirt removal is an option and additional cost.

1. Get the pH up before SLAMMING because the pH may not be reliable above 10 ppm FC (SLAM levels). 2. CYA is harder as even after you add some, it won't be fully dissolved for 24-48 hours. You don't want to add too much but you need some so the chlorine will last in your pool. When to Test...

The FAS-DPD chlorine test is the one where you add a couple scoops of a powder and the water turns pink then you add drops and count how many it takes to make the sample clear.

What type of test kit do you have? Hopefully you have a tf-100 or Taylor test kit with the FAS-DPD Free Chlorine test. Your signature and Poolmath logs say your pool is 13,500 gallons - adding 1-1/2 gallons of 10% chlorine should raise your FC by 11. But you do need to test.

You can just replace the motor and keep the wet end of the pump if you want. There are VSP motors that will fit your pump. Pretty sure I bought my motor from Inyo.

I turn the pump off, yell at everyone in the house to not turn anything on, go look at the meter's instantaneous watt/kwatt reading, turn the pump on, check again, buy ice cream for everyone I yelled at. Also I can get hourly kW graphs/data from my utility (PG&E) and if I start my pump early in...

Did You pass the OCLT?

Sounds like you need to SLAM. To be sure you could do an overnight Chlorine Loss Test (OCLT), Description for both is in the Algae section of Pool School

If your pool is 33000 gallons 1.5 to 1.75 gallons is 5 ppm. PoolMath will show you that in its Effects of Adding section.

Your pH will probably rise slowly and you'll have to add some more later. Even without knowing your pool i imagine pH will be good for at least a week. As long as you test often enough you can add more before it gets too high. For MA additions it is important you don't add too much. If PoolMath...

To waste wherever you have that plumbed - same place your DE goes when you backwash. You will need a multiport valve for a sand filter also.

I have a sand filter which works just fine for me. If I needed to replace it, I would probably go with a large cartridge filter based on what I've read here. When I bought the house, oh so many decades ago, it had a cartridge filter and it just did not work, I switched to DE and then to sand. I...

We can see your PoolMath logs. You definitely need to add some liquid chlorine to get the FC up. If your pool is 33000 gallons you need to add a couple of gallons of 10% chlorine just to get it in range. Adding a little too much chlorine will be OK. PoolMath has an "Effects of Adding" section...
