The Mineral Plus+ Calcite Cartridge System adds back in the essential minerals (calcium & magnesium) to your drinking and cooking water which are removed from RO systems and Ultra filtration systems.

What does the Calcite Post Cartridge do? back to top
When installed after an RO system, this cartridge adds beneficial and needed calcium and magnesium back into the water. RO systems remove nearly 99% of all minerals and anything else from the water. Adding this after your RO will help keep your water balanced and full of beneficial minerals.

Happy Camper

I actually think that your system has made my pool maintenance much easier. Before I installed it I was constantly having to scrape the border tile to remove the calcium deposit, now I rarely have to scrub it and it seems that the calcium is deposited on the bottom of the pool and all I do is vacuum it and this has made me recommend your system to others.

Very Pleased

I am very happy with my new whole house water system that takes out not only chlorine, but fluoride too. My hands are not dry from doing dishes like they used to be. My skin feels so soft. And, the water is delicious to drink. There is nothing better to have in this world than good water. May I add?....the Pelican representative was a man of his word. Pelican is a business that you can trust.

I contacted Pelican Water Systems by phone and spoke with Mr. Mark Hughes and was pleasantly surprised on how friendly and helpful he was addressing all my Questions and concerns. When meeting Mr. mark Hughes in person he was very professional and knowledgeable. I felt very comfortable purchasing my whole house filter system. Thanks for the great customer service.

Wonderful Solution

Salesperson, Patrick was very helpful in helping me decide on the proper unit(s) for my home. My initial problem was mineral buildup on shower heads and faucets. Plus the hardness and quality of the water varied as the municipal supply changed over from reservoir to well water during the year. With the new Pelican system I don't worry about hardness or impurities and get a much better tasting supply of water for my home. Thank you for a wonderful product...

Happy Customer

Because I have more than one Pelican product, it's just easier to address the wholesale satisfaction my family is getting from the systems. The Whole House Carbon Filter to the Shower Head with Aromatherapy systems are great!

Great Experience

I live in an area with very hard water and noticeably high levels of chlorine. One of my children battles eczema and there are countless articles about the negative effects of showering/bathing in chlorinated water—for everyone, but particularly for people with health issues. I had poked around for a couple of years but ultimately I chose the Pelican system because it does not require a system flush (i.e., water waste) and because of the significantly positive reviews. This system is fantastic and delivers on both quality and taste. We noticed results immediately but once the carbon tank has been active for 30+ days you really start to see the benefits. Our water tastes better than bottled water and no longer smells of chlorine. An added benefit is the significant reduction in hard water deposits we used to see on our fixtures and shower doors not to mention how much softer our water has become. Lastly, I have been able to let my son sit and play in the bathtub knowing that he isn’t sitting in harmful water and we have not seen one flare-up since our system was installed. I would absolutely recommend this company. A+.

great product, easy install

I ordered the combo series PSE 1800/PSE2000 along with post hot water filter after the tankless gas heater. everything was very easy to install. water seems great. I love most though is not going through the hassle of adding salt. It saves on electric and doesn't waste any water
