Welcome to our forum.
Congrats you will love it I’m sure as much as we enjoy ours. Spring is a ways off. Is it do to weather and installation? Where do you live?We got ours when the weather was still nice and had a chance to get used to maintaining it when it wasn’t winter. That is most likely a good thing. But we do love ours best in the winter months. What method of sanitizing will you use Bromine or @ease chlorine? I would recommend the @ease.
With regards to chemical I have NO IDEA. I guess that’s the next step in my education. We’ve never had a pool or hot tub before so I don’t really know squat about water chemistry or maintenance yet. Cheers.
