Not really. It just requires a basic understanding of water chemistry and a simple schedule. But it's not expensive. All you really need is some chemicals and testing supplies which is about a low monthly investment.

They’re on the job whenever your hot tub’s running, and your hot tub filters need a good cleaning to work properly. You can clean them using three methods: • Rinse • Spray • Soak Rinse your hot tub filters as often as possible with warm water or your garden hose, especially if you’ve been using your spa more than usual. Spray your filters every week or so with a hot tub filter cleaner to provide a deeper clean. Don’t forget to rinse them after. Soak your filters in chemical cleaner every time you drain and refill your hot tub to extend their life and loosen any stubborn particulates. Rinse them thoroughly afterward. When your filters get to the point where even a chemical soak doesn’t completely clean them, it’s time to replace them.
