Hello Jonas,
I have been following your intex poll construction to the deck, and I'm on my way to do more or less the same despite I'm going to keep the metal frame. Intex has a XTR Ultra frame that seems to not rust like the standard ultra frame.
I'm leaving in Kokkola, in Finland (same latitude than Umeå but other side of the sea cost), and winter get minus temperature for about 4 month with of course snow and temperature as low as -5 to -25°c most of the winter.
I'm wondering how do you do with your pool in Sweden during winter time, especially with the liner and pump. Are you removing them every automn and store them in positive temp. room or do you leave them in place? what do you do for it to not get damage?
I will be glad to get your comments to let me go forward in my pool project.
Regards,
Damien
