Total rookie here. I'm still reading and overwhelming myself with the wealth of info on this site, but if you could help me with my checklist, I'd appreciate it. Aside from the building materials, once I get the pool up, what items are must-haves? So far I've bought the 22x52 Intex pool, Intex 2650 sand filter/pump, and the Intex SWG. On my shopping list I have: the Hayward SP1091LX skimmer, Wanda the whale, and the TF-100 test kit. What else do I need? Which winter cover do you recommend? Do I need a solar cover and if so, which one is recommended? TIA!
