I'm quite new to this stuff and have an older Marquis Reward, using the set up and supplies the orig owner had; In-line Spa Frog - bromine/mineral cartridges.
Working well with added shock a teeny bit here and there based on use or once a week. Bather load for us is low, just two of us most of the week and staying pretty consistent on everything.
I did set mine as the default too but got familair with steppping through the options on the panel just to understand it better. Filter duration time can be changed too, on mine anyways.
Had a few minor bouts of slightly cloudy water or foaming but I beleive it's self induced or some sloppy chemistry on my part. Most of the 6 weeks we've had it going have been perfect and trouble-free / crystal clear. I'm sure you'll fall into a rhythm or routine that works for your use and it isn't an over-night process. For me, the learning curve is the -only- way to get confidence so a few stumbles or a step backward really isn't a set back at all. I'm already finding the testing or maint of the water is actually pretty relaxing itself. Just another reason to be outside in the fresh air.
Enjoy -
