The only way to spa!
I'm a second time user. Had an Aero-Spa at my previous residence for three years, and left it with the home buyers after quickly showing them how to remove all fears about hot tub maintenance! Bought a new tub with our new residence, and just for kicks, tried out the new salt water chlorinating system for a year. It was ok. Required a bit of regular maintenance, but I didn't care for the salty smell on my skin afterwards (smelled like I'd been at the beach all day). A year's worth of cartridges for the salt system cost $300. So when it was time to change the water out and order a new pack of cartridges, it was a no-brainer to go back to an Aero-spa instead. No regrets, no maintenance, no showering after use to get the funky smell off! I use a cap full of Spa Shock every two or three weeks, or whenever I think about it, but my wife and I are the only people who use the tub, so I don't worry much about that. I'll share a tip: Our spa cover is attached at one end, so I used some loosely applied zip ties along the framework and center rib of the spa cover to suspend the Aero-Spa tubing out to the middle of the tub, where it then hangs into the deepest part. Now when we open the spa cover, the Aero-Spa tube and crystal come out automatically with the cover. Close the cover and the tube and crystal automatically fall right back where they belong. It just doesn't get any easier!!
