Item in-stock

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.

excellent product

My wife was having scalp issues with the water here in Ft. Myers. As a stop gap measure I ordered the filter hoping to correct or relive the problem. The filter was the answer and everyone is happy! One day service didn't hurt your cause either.

Over all does as advertised, better tasting, softer, less scale, so is doing as advertised. NOTE; the installation by Jim's Plumbing here in Pahrump was great ++, R. E. Pike

Professional and welcomed service.

So about a year after moving to the country in Virginia, I was about to do a major kitchen remodel. But before I was going to drop $2,000 dollars on new appliances I wanted to make sure the water quality was not going to degrade my new appliances faster than normal. With my well water being slightly acidic I needed a way to raise the pH and Pelican was happy to help. They spent about 45 minutes on the phone with me to determine what products would suit my needs best. By the end of my phone call I had a new carbon filter and a calcite tank ordered and would arrive in about a week. It's been 4 months since I installed the products and our water quality is much better. Our water tastes great right from the tap, our skin and hair fell much better after a shower, and our laundry feels better to the touch. To sum up: Great products, great customer service, and better quality of water. When friends ask I'll be sending their business to Pelican.

Pelican shower filters

I struggle with dry hair dry skin when I moved to Texas. My hair felt like a Brillo pad and I always had an uncontrollable itch. I later realized it was hard water that was causing the problem. I purchased the Pelican shower system and noticed a change. Als I need to mention the excellent customer service provided. I received my product quickly. Thanks Pelican.

Matt - most helpful

To Whom it may concern: Matt has been very helpful as we have been evaluating our changing needs while wanting to keep Pelican as our supplier for our water system needs. We had been purchasing bulbs yearly but now have determined we don't need to, as the amount of water used averages to usually less than 300 gallons a day. When we do need anything associated with our Trojan Max be assured we will be calling on Pelican as you have always served us well and as Matt has continued to work out how Pelican might best meet our needs. Sincerely, Linda Campanella
