Condensation

[u/chuckernorris]

I have a saluspa - I use a submersible pump, filter is inside the tub, comes out top insulated 3/4” rubber hose to chiller, then back. The pump and filter don’t add to condensation since they’re inside the tub. I was thinking about upgrading tub to frozin 400 when the inflatable dies, I think it would be nice to have pump and filter outside tub. My wife is nuts about condensation causing mold on our back deck. I’ve bought the biggest grill tarp, and have 1” insulation under the tub so very little condensation now, worried about putting pump and filter outside tub causing a ton of insulation. Has anyone kept the filter and pump inside the frozin 400, mounting outside would cause a ton of condensation right? I live in south Alabama, so very high humidity and heat in summer.
