Are my Startup Steps and Maintenance ok?

[scorpionc53]

I would like to run my startup procedure and maintenance schedule by you folks because A. I'm a new owner, B. I'm not a chemist, C. I'm good at following direction, and D. I received multiple products with my tub.

I own a 2019 Hot Springs Relay, it holds 345 gallons, keep it at about 103F, and use it 1-2x per week, sometimes an extra couple time on weekends with more people. I just had a problem with getting my FC up for more than 8 hours and simply bit the bullet and drained it. Frog, the inline folks, told me that my spa likely had too much chlorine in it and it was ready to be drained, so I did.

Below are my steps for startup and maintenance, chemical wise. Please let me know if it looks good, you see something wrong, or have other suggestions.

1. Refill water to 1" below seat pads.
2. Re-install filter
3. Purge pumps.
4. Let warm up to 90 Degrees
5. Adjust PH and Alk as necessary. I use PH + and PH- by Pro Team Spa to set these values. If Alk is low, I also have Alk + by Pro Team.
6. Check hardness(I use an RV drinking filter to fill the spa, so my hardness is usually on point the last 2 fills).
7. Add Pro Team Spa Gentle Spa per directions
8. Add Pro Team Spa Metal Magic per directions
9. Super Chlorinate with 1.38 TBSP of Dichlor by Pro Team Spa
10. Once my FC has dropped back down between 1 and 3, I'll insert my Frog Mineral and Chlorine cartridges.

If that looks good, onto maintenance.

Usually every time before I jump in, I shock with Pro Team Spa oxidizing shock, let it circulate for 15 mins or so, sit in the tub for an hour or so, then close it up. And that's about it. My Frog system typically keeps the chlorine levels in check, and I check the PH and Alk once a week.

Should I be doing something else? More, Less, A-OK? As I said, I'm not chemist, but want to see if I'm doing too much, not enough, or just right. I get somewhat confused when I'm mixing different brands, or when my chlorine levels get out of whack. Or when I'm supposed to add in shock(Pro Team Oxidizing shock) vs. more dichlor if at all. I also have a few others that came with my kit such as foam fighter, blue clarifier, etc. 

Thanks in advance!
