I have a hot tub with a CSWG. I add borates to the hot tub, just like I do for our swimming pool. I had some foaming issues. The fact that I keep CH at zero makes my hot tub very susceptible to foaming. Per TFP, I started using Spa Perfect. That helped a great deal.
Last weekend about 16 teenagers displaced about 1/3 of the water out of the hot tub. After refilling, I added borates.
It then occurred to me that perhaps borates and Spa Perfect might not go together. The Spa Perfect instructions say to add when FC is less than 3 ppm. I assume this is to prevent the FC from quickly oxidizing the Spa Perfect.
Do borates render Spa Perfect less effective?
I was not sure whether to post this question here or in the water chemistry forum.
Thanks for your help TFP!!!
