I have well water. Tested yesterday at 26 ppm nitrates, 16 grains hardness, 0.1ppm iron. I also have conventional septic system

Family of 5. 4 girls and they use alot of water!

Current recommendation is a WaterCare Trident Softener with estimated regen every 4 days and a Kenetico K5 system for kitchen sink and refrig. $3200 installed.

I searched online and found a RainDance system called Nitrate Eater that is an ion exchange softening system to remove nitrates and soften water.

Looking for experience to guide me in the purchase.

Is an undersink RO better option vs ion exchange for nitrates?

Has anyone had experience with the softeners cited above? Particularily the RainDance system as it is the only one I found that does both.

Are box store under sink RO's as effective as the K5?

Would I still want an undersink RO if I use the nirtate eater. Other than nitrates water quality is extremely good from a drinking standpoint

 

I've used a Reionator for the same purpose. It has a mixed bed (cation & anion resin). Check out the web site.
