My husband and I decided to create our own natural hot-springs experience right in our back yard. We have all the tools we need to make any kind of water we want, so we used them to create the perfect spa water. After setting up the spa, here are the steps we took to fill it with perfect spa water:

1. First we used Ionia's Super S-12 water ionizer to make many 5-gallon jugs of acidic water (one at a time). Note: This took several days, because the SuperSanitizer isn't a commercial water ionizer. We had to give a break after every 5-gallon pouring and we only poured about 50 gallons per day.
2. We mixed some of the alkaline water in with the acidic water until each of the jugs were the pH we wanted (about 6.8 pH). The reason for this pH is that it's really perfect for the skin to have the pH a tiny bit under neutral. We didn't want it too low, though, because if it got too close to 6 pH it may adversely affect the spa's plumbing. Having the SuperSanitizer water ionizer allowed us to perfectly adjust the pH to exactly what we wanted without having to add chemicals.
3. We tested the pH of the water made using our pH reagent drops. This is important, because we've found that the pH test strips made for pools and spas are extremely inaccurate. Note: Once the tub was full we found that the pH stayed consistent. So, unless we have to add new water we don't really have to test the pH much any more.
4. As a final step, we poured our perfect pH water through our John Ellis Machine. Doing this increased the hydrogen bond angle, making the water additionally therapeutic. Extra bonus: John Ellis water is anti-fungal, so has a sanitizing quality about it as well.

We just kept doing 1-2-3-4, above, over and over until the spa was filled. It took quite a while, but it was worth it. Now we can go to "Hot Springs" every night!

Sanitizing our Perfect Water

We didn't want to spoil the all-natural appeal of our beautiful spa experience with harsh sanitizing chemicals, so here's how we handled that:

1. Before even filling the spa with water, we put a large tent, with mesh sides, around the spa. This protects it from insects, leaves and other biological contamination from nature. We also keep the lid on the spa when it's not in use.
2. Our spa has an ozone cycle (where it pumps ozone into the tub twice a day at times we're not using it). This is sanitization step 2.
3. After filling the spa we shocked it with non-chlorine shock.
4. The next thing we did was to add a mineral sanitizer cartridge. This cartridge contains silver and copper balls, and gets stuck right in the middle of the spa's filter. Super simple. It will last 6 months, killing germs, viruses and anything else biological that should get in the spa.
5. Finally, to be sure we were fully protected, we added natural enzymes, made for spas. These enzymes break down and consume anything biological that may enter the spa water. We have to put another bottle of enzymes in about every month.

That's it. It wasn't too hard, and the water in the spa will last for about six months, when we will have to do it all over again. We really enjoy our all-natural, therapeutic spa. We use it every night. 

Here's a  you-tube video summarizing what we did: 

Note: I'm adding this note over a year after pouring the spa. We add the enzymes every so often (about monthly) and if we notice any odor or color we "shock" it with non-chlorine shock. We've had to shock it about 3 times, total. We've also had to add water a few times, and when we did, we used the same process as described above. That's it! So, it may seem like a lot of work, but it has lasted us a very long time.
