Ground prep for spring install of Splash pool question

Good morning all,
I've lurked here for a bit and read enough threads to make my head spin, but figured I'd actually post my setup to get some thoughts on what I should do for my install. I am installing a 17x29 Splash Titan (now just the blue version of their superpool) in the spring. I went a Splash pool this because I have family who have them and swear by them. One has been up for 25 years no issues in PA winters, just winterized like a hardsided pool. I have leveled the ground (area of 24ft by 36 ft) and checked with a transit to ensure the whole area is within 2 inches level of itself, a lot of it is within an inch of level. I am undersure how I should finish it maybe either with mason sand, crusher run + foam, or something else. The topsoil has all been removed and we're down to undisturbed earth which is a clay mix soil that can be pretty hard. Unfortunately, given the nature of the soil, it's very hard to make it completely dead level in order to just put foam on it, pavers and call it a day. The lowest area which is the open end was about an inch lower than the rest once the top soil was remove so I dressed it with some #57 I had to bring it up to the rest. It didn't take much and I probably didn't need to but I had 2 scoops left from dressing my driveway earlier in the year. For the Splashpool, I can get the option leg blocks if needed but then I wasn't sure if I needed them + pavers or maybe just the blocks on sand / crusher run. To make things easy, I have access to a quarry 3 miles from my house that I can use for base materials.

The whole area is being reworked to includ deck on the highside, paver patio on the lower area, etc.

Let me know your thoughts and thanks in advance for the read!

QP / Crusher Run is also very hard to get level. It makes an excellent sub-base though. Use stone dust for your final top layer. If you have to come up more than an inch, then use QP (compacting it first) first, and your final inch is stone dust. Stone dust will compact very well, but is a lot easier to screed level than QP.
 
Perhaps this can help.

I'm wondering if I could use a pad/weed fabric to seperate ground from stone dust (maybe not needed but then they wouldnt mix), put down about approximately 1 of stone dust and then 1/2in foam over it? If I use the SplashPool's Footblocks that support the bottom of the legs, do I need the pavers? I wasn't sure if the paver/footblocks should be buried or ontop of stone dust. Again it would only be approximately an inch deep or so of dust and I could always sweep it out of the way during install. I checked out the post Derek shared (Jim's AGP Journey) and in that it looks like pt lumber/pavers right ontop of the stone dust? I do have a plat compactor I can use on the stone dust as well.

I don't think weed control fabric would do much. A geotextile might, but not weed control.

I'm not that familiar with SplashPools but my understanding about those kind of pools is that PT Lumber is better. The shape of the leg pipes leads to a concentrated force along a line, which can split a concrete paver.

Okay I was looking at a few of the different options folks talked about on the forum. I'm thinking layering it as follows. Dirt -> liner -> stone dust -> XPS foam - > pool. Unless I should maybe go dirt -> stone dust - > foam -> liner?

As for the legs, here is a picture of the legs with footblacks for them. It's designed to spread the load over whatever the base is. It's like the grandfather of the Intex, on steroids lol. The liner is warrantied for 20 years, legs and such are 10 years. I intend to take them up on their offer of all stainless legs though.

Maybe they spread the load enough to either just use directly ontop of the stone dust without pavers or maybe still have to put pavers under them.

Thanks again for the insight!
