Solo,
Congrats on the tub!
Here's a chemical routine that was posted by someone else when I first asked the same question
Per Use add one teaspoon of dichlor per person after each use
Thursday Shock tub with MPS
Saturday Rinse filters with garden hose
Sunday Test water for chlorine, pH and alkalinity adjust as necessary
Monthly Clean filters in a commercial filter cleaner
303 the surface of your cover
Tri Monthly Drain spa and clean all surfaces and refill
That's it in a nutshell
Enjoy your new tub
