The pH range of the Ultrastream is generally from 8 to 9.5 depending on the quality of the source water.
The H2 level will be about 1.2 to 1.5 ppm also depending on the quality of the source water.
They are not individually adjustable.
The Ultrastream works very much like nature.
The levels of pH and H2 are going to be determined by 2 factors:
- hardness of the water
- and the length of time the water has in contact with the media.
If you have hard water, that's good because it means it's high in mineral content BUT it can be a little hard on the magnesium used to create the H2.
For those that want the highest pH and H2, we recommend you run the water at the rate of 1 liter per minute to give the water a longer time in contact with the media.
