New Master Spa Lsx800 Questions

[Dave48103]

Hello spa owners! I'm new to this community and to spa ownership. We've had our Master Spa LSX800 for a couple of weeks now. Absolutely love it, no problemss. But I do have some questions for other Master Spa legend series owners:

1. Is this spa not able to be in heating mode while 2 pumps are running? Not a problem now, but I can see this as possible issue when winter comes and the tub has more than 1 or 2 people in it. The owner's manual makes no mention of this.

2. Given that the tub has a 24 hour continuous cycle pump for filtration & heating, does the other pump cycle feature have any use? Even though it says it will run for 15 minutes at a prescheduled time, it only runs for a minute or so. The manual seems to imply that the cycle is disabled with spas that have the 24hr pumps, but ours does run for a bit. I'm just not sure why?

3. What do people use for a "shock" when you are using chlorine instead of bromine? The dealer gave us Spa Boss "Energize", but that seems more compatible with bromine.

4. Does pump #3 (the "therapy" seat) have a low speed? The other two pumps controlling all the other seats both have a low/high setting

BTW, I installed an inexpensive kwh meter just for the hot tub so I know exacly how much energy it's consuming. So far, with using it every day for 2 weeks, it's cost $15 (will be much higher in winter), but happy with that energy consumption so far.

Thanks in advance!!!
