I'd maintain your pool for you, but I live in Florida. If you hire someone, I think the only thing you'll have to worry about is the pool guy keeping calcium in your pool. I say this because it is one of the most neglected chemicals at least where I'm at especially on SWG pools. This is because they're not getting a steady diet of Cal Hypo like standard pools. For a liner, not so much of a big deal. But I see you have pebble tec. Algae really shouldn't be an issue with a SWG. I rarely have algae in salt pools. Usually high phosphates is the issue if there is.
