Finally installing. A few random questions:

[badutahboy]

HEy guys, I'm finally getting ready to install my new pool (atlantic vantage 18x33 buttress free)...

As I was reading through the directions I had a couple questions about things that either conflict with information I've read here, or have never been addressed here to my knowledge..

1. The instructions say to put patio blocks underneath the ends of the rails... I've seen on here that it's not totally necessary.. Is there a solid answer to this? I live in Utah, so we get frost, but my soil is very solidly compacted already.... so much so that digging a hole to plant a tree proved futile yesterday..

2. The instructions say to fill the trenches with crushed limestone.. Is this necessary, or can I just re-backfill them with the dirt I pulled out? I don't see the structural advantage to limestone, since the trenches run across the middle of the pool, and I don't think you'll see an imperfection in settling of the trenches, because I'm using 1 1/2" foam under my liner.

3. Can I spray the ground with triox today, before installing the liner (I'll do it multiple hours before)? I had a few weeds coming through the dirty, and I want to try and make sure I don't battle them... ALso, will this even be an issue, since I'm using the foam under my liner?

4. As I said, I'm using 1 1/2" foam under the liner.. I also have the little 3" sticky back cove from the dealer... Is there any benefit to creating a sand cove, given my situation, or will the foam cove/styrofoam bottom suffice?
