The PHPLUSKIT-38 cartridge is a super high capacity, naturally occurring PH increaser. It is for general drinking water pH increase purposes. It can also be used as an reverse osmosis polisher if desired (installed at the last stage). Since it is sacrificial, the calcite acid cartridge will add 2-5 ppm of hardness to the water. This is also an excellent way to reduce the corrosiveness low tds water.
This filter is constructed totally from FDA grade materials and media. This calcite filter will deliver a neutral effluent form acidic feed as low as pH5. Low pH's require slower flow rates.
One of the advantages of Calcite is its self-limiting property. When properly applied, it corrects pH only enough to reach a non-corrosive equilibrium. It does not overcorrect under normal conditions. Upon contact with Calcite, acidic water slowly dissolve the calcium carbonate to raise the pH.

No more post-RO acidic waterI included pics of the effects of the filter. Using a liquid test my straight tap water was blue-purple. I'm going to say pH between 7 and 7.5 based on the color chart I was given. After the RO the water is a pale green with
some yellow. That is around 5.5 to 6. That is typical of course for the RO system to reduce the pH. After installing the pH "filter" my pH rose to around 7 (since it should be self-limiting that's all I expect). In addition, my TDS after the RO originally was in the 20-40 range (down from 500 before RO). After adding the pH "filter" my TDS is now around 120. I notice just barely a difference in flavor. Another added benefit is that I can purchase this fancy automatic coffee maker I wanted. The manufacturer states not to use typical RO water with it as the TDS would be too low. So in summary, this worked much better than I expected. I repeated the test because I was surprised. Similar results.

Water NeutralizerI add this the my system this year and so glad I did. There is a big difference in the taste of our water. Taste better than bottled water

system upgrade to Mineral systemexcellent decision. water is cleaner softer taste than before. easy, very easy to add on to the system. took all of an extra 5 mins while replacing my filters. you do need to run the tank empty a few times to get the white (Over mineralizing out) but again. I drained the tank via the sink outlet we drink from. all of 5or 6 mins. closed it, set a timer for an hour and did it again. done and water is better than ever.

water neutralizerDid not help neutralize the water as the meter indicated the water was 5.0. The company sent another filter with additional minerals added. The water acidity improved with this filter, but is now, about a month later, acidic again (5.5 ph).

Increased pHI added this filter to my RO-Hi system to increase the pH. Quick and easy installation with no tools needed! Increased my pH from 6.1 to 7.0 with great tasting water. Very satisfied.
