We have a 680 gallon hot tub that is almost 2 years old. We did tons of research about using non-chemical products in the hot tub. I found 30 pages of testimonials on the Pine Hill Group (yahoo groups). Here is what we do. When we fill the tub with fresh water we put in 5 drops of Geranium. That's it. We change the water 2-3 times a year. About once every 8 weeks or so we add 1-2 drops. We have a large garbage can with lid that we fill with water plus 1 cap Thieves household cleaner. My husband hoses down the filter with a high pressure hose and then soaks it overnight in the thieves/water mix. Then he hoses it down again and puts it in. We alternate with 2 filters. That is it. Our tub is always crystal clear, no scum, no slime, nothing.....just beautiful smelling clear, clean water. Hope this helps.Wow - that is so exciting to me, to think that you can use Geranium and Thieves Household Cleaner, instead of expensive, toxic chemicals.
The choice of Geranium is an interesting one. Although not one of the top infection fighters among essential oils, it does have a fair amount of anti-microbial properties, including fighting fungal infections.1 In the Essential Oils Desk Reference, it says that historically, Geranium has been used for regenerating and healing skin conditions, so isn't that wonderful to have in the hot tub! It's fragrant influence is to help release negative memories and eases nervous tension. It balances the emotions, lifts the spirit, and fosters peace, well-being, and hope.2 In the auricular emotional release taught by Gary Young, Geranium is the oil that is used to release issues with "mother", or female. Hence, I call Geranium "the mother oil". When we get new calves, sometimes I will go out and put Geranium on their ears to help them with the separation from their mother.
I love the Thieves Household Cleaner! It has replaced almost every cleaner in my home, and I love the fact that I can clean and inhale without having to have the windows open, the fan on, and wondering how much toxicity I am breathing in. This cleaner offers a non-toxic, biodegradable, all-purpose cleansing solution using therapeutic-grade essential oils as emulsifiers and germ killers. It is fully biodegradable and complies with EPA standards.3
Now, I'm ready to go to Jane's and get in her hot tub! :)
