Hello,
I had a pool and got very comfortable with the TFP methods of maintaining it, and loved it! This place is awesome. Now I no longer have the pool, but I have a 2008 Hotsprings Jetsetter JJ Spa (225 gallons) and I have several questions in general about spas, but more specifically with using a SWG. I had an intex spa, which is when I bought the Cholormatic SWG which worked pretty well, but never took the time to really learn about SPA chemicals/treatements. So here are my questions:
I had a pool and got very comfortable with the TFP methods of maintaining it, and loved it! This place is awesome. Now I no longer have the pool, but I have a 2008 Hotsprings Jetsetter JJ Spa (225 gallons) and I have several questions in general about spas, but more specifically with using a SWG. I had an intex spa, which is when I bought the Cholormatic SWG which worked pretty well, but never took the time to really learn about SPA chemicals/treatements. So here are my questions:
- I'm using the poolmath app on the iphone, I don't see a hot tub setting? Are all the recommendations in the app the same for a hot tub, or do they need to be tweaked?
- Does anything with the ozonator that's in the tub change any setting recommendations? I understand it just helps with using less chemicals to maintain?
- On the SWG, it recommends 1.0-3.0 PPM FC, but in this forum and app it recommends higher, which should I use? (I'm currently at 1 ppm and trying to learn how long to run the generator to maintain the appropriate level). My bathing is typically 2 people every evening, not showered. Does this change the recommendation?
- Is it just a matter of testing after bathing to make sure there's some FC remaining until the SWG kicks on for it's next cycle? It also has a boost mode, should I just be hitting that after getting out?
- On the SWG, it recommends hardness of 200-400, I'm at 125, which seems to be in line with the TFP recommendation, is this okay with the SWG?
- On the SWG, it recommends "0" stabilizer, I imagine it's meaning CYA? I see the TFP recommendation is 30, but doesn't discuss SWG. If I'm only using the spa in the evening (no sun), I found it interesting CYA is recommended with TFP. Does it really need to be in there with using a SWG?
- Lastly I've been battling the TA and PH, this seems to be the trickiest part of the spa balance act! I was well above 8.0 PH, and TA of 130. I had some Sodium Bisulfate that was given with the spa. I added that until I accidentally overshot to below 7.0 ph and TA @30. I then added Sodium Carbonate, and overshot the other direction! So I'm back above 8.0 PH, but my TA is at 50 (which I believe is recommended). I'm sort of confused on the balancing act between the two, and how to find the sweet spot. So questions to this:
- If TA is good, is Sodium Bisulfate what I should be using to bring down the PH? I get the feeling it's going to bring my TA down too low again? What should I target for PH on the way down? Is there a better chemical for bringing down the ph without bringing down the TA?
- If/when my PH is low, but TA is good, should I be adding chemicals to bring it up, or let the aeration bring it up naturally? Is Sodium Carbonate what's best for bringing it up?
- Is it okay to add/retest in both directions in the same day? I read somewhere to not increase and/or decrease with chemicals in the same day. Since I over shot it up today, should I use chemicals to bring it down today after waiting some period of time?
- When PH increases due to aeration, does it automatically bring itself down? Or it will always be necessary to use chemicals when it climbs up above 8?
- I don't see a Sodium Bisulfate or Sodium Carbonate option in Pool math, what are these referred to in there? (I bought the clorox brand)
