We have been under a load of pressure from certain health groups to produce an RO system which offers a pH of 8 - 9 . It's taken us 6 months or R&D to develop this filter combination and a further twelve months of testing to reach this point.
This is the ultimate in pH adjustment, it's the only alkolizer cartridge in the world that can raise and retain a constant 8.5 pH over 12 months and we believe well beyond this time, however our testing period only covers 12 months.
This a special grade of Magnesium which is very sacrificial so it lends it's self to a very quick rise in pH making it suitable to post RO work.
Like all sacrificial alkoliser cartridges this one will leech a small amount of magnesium into the final drinking water. The rate of magnesium introduced will vary from each situation but testing has shown on average an increase of approx 20-45 ppm.
This cartridges needs to be pre-flushed to clear any fine particles so we suggest a wash time directly off the mains pressure or approx 3-5 minutes prier to use. Any system containing these cartridges have already been pre-washed but replacements are sold dry and require pre-rinsing.
Even after rinsing it's likely the TDS may be as high as 70 - 100 ppm depending on the rinse times and methods but this will quickly decrease to the average output.
It's essential that the GT6-11 XstreaMn carbon cartridge be use after the XstreaMn GT6-0 Alk cartridge for maximum taste reduction. So you should order both cartridges at the same time if you are no currently using the XstreaMn alk system.
The life of the cartridge will be dictated by the pH result. If you see the pH of your final water dropping below a point you are satisfied with, then it's time to replace the Alk Cartridge, we feel this will be between 12 and 24 months.
