420G Spa. Spa Frog System. Struggling With Water Chemistry
Guest posted a topic in Hot Tub Water Chemistry
The day before Thanksgiving our new 420 Gallon spa arrived. We are quite excited, but I am struggling with getting the water right. It does have an ozonator (but how the hell do you tell if it's working?!?!?). I am using the Spa Frog floater system (bromine). Startup/Fill: Filled tub from the hose Heated the tub overnight Put in the Spa Frog "jump start" capsules I opened the Spa Frog mineral and bromines to 6 and floated them in the tub After the fill I couldn't get my alkanlinity over about 60 without PH spiking to 7.8 or higher. CH was low so I added the stuff the spa store gave me to bump it up to 160-170 consistently. PH has been staying 7.4-7.6. Here's where I am struggling: FOAM! We have a good amount of foam that I can't seem to knockdown What do add - how much of the MPS "shock" do I add, and when? The container (Amerse) says 2 ounces per 300 gallons weekly or after every use. I have a friend with the same tub that never adds it and his water is fine - mine has been a little cloudy. I used the tub on Monday of this week and then added a half-dose of the MPS. I was out of town until yesterday and when I got home my water was cloudy, there was a residue at the waterline and it smelled like chemicals. Immediately tested and PH was a little low and bromine was .1. I shocked with MPS and bromine spiked to 9.1 before we had to head out to dinner reservations (i am sure it went over 10ppm) What do I use: ColorQ Test Kit Amerse chemicals Spa Frog Am I just not adding enough MPS after each use? My wife and I probably spend 4 nights a week in the tub, 30 minutes at a go. So that's 4 hours of use weekly. Do I really need to add 3 ounces of MPS after each use, or once I get this damn thing stabilized can I do weekly treatments? I thought the Spa Frog was supposed to make life easier... THANKS!
