Anyone with experience in leaving Intex Pool up in harsh winter?

This is my signature:
Intex 18' X 48" Ultra Frame AGP 6700 gallons | Two Intex CS8110 SWG's | Hayward Pro Series 21" Sandfilter | Hayward 1.5HP Power Flo Matrix pump | Hayward Thru-wall Skimmer | Wanda the Whale | 72 sq ft of Sungrabber Solar Panels with Hayward GLC-2P-A | Taylor K2006 Test Kit, Sample Sizer & Speed Stir | Click Here To Become a TFP Supporter!

I notice you have6700g for your pool. How did you come to that as 18x4 is supossdly 7600? I did notice that7.6 can't be right based off pool math I always use a little less bleach been~ to 7k. Do you think one could do the job at a high%? I think I read that intex does not have% control so not sure if could just cranck her up. Also I have a 12" intex sand filter #sf80110-1. Per intex18x48 is well in the range for what this pump can handle. I have the two intake one return model. Is this sufficient?

Top ring first of course.
Edited. All that plumbing looks a bit overwhelming. Did you worry about pitch at all or does your pump have that much pressure to run all those add ons?

An 18’ X 4’ Pool, filled to 42” deep holds 6700 gallons of water, and that 6700 gallons works out perfectly chemical wise.

I had the Intex 14” sandfilter with 3/4HP pump, used it for two seasons with no major issues. By biggest gripe about it was a lackluster vacuum performance, and (what I now realize) insufficient flow to keep my solar system efficient. The new system has more than enough flow for my current & future plans.

In the peak of summer I had both SWG units running 6 hours each, so one unit would need 12 hours in my pool.
