Hi,
I have a new spa. 300 gallons. I'm sanitizing with bleach, per the instructions in the sticky. About a week and a half in and the water chemistry remains stable. CH is 150, pH is 7.5, TA is 65. The spa is indoors and covered. I haven't concerned myself with CYA under these circumstances, since it sees so little sunlight, none directly. Should I still bring up the CYA?
I am getting a fair amount of foam when the air is on, and a bit of a "new spa" plastic-y smell. Is that to be expected? Does it decrease over time? Is there anything I can add to help with the foaming?
I'd like to add borates, as long as it doesn't add to the foaming issue. I'm hoping that will help even out the highs and lows of the sanitizer. But maybe I just need to add CYA... Poolmath indicates 18 oz of 20 mule team, plus 8 fl oz of muriatic acid should get it to 50 ppm. Are these gradual additions, or just dump it all in and mix it up? (I don't add borates to my pool, so I have no experience with the process.) I'm also a little concerned because that seems like a lot of stuff (acid, particularly) to add to this small volume of water.
In short, CYA? Borates? Both? Do those calculations look ok?
Thank you in advance! This forum has been a great resource for my pool. I'm hoping it makes spa care just as simple.
