"I replaced my resin with Resintech CNS10 Premium 10% Crosslinked Water Softener Resin. My water hardness level dropped about 30% from the best readings I had with the prior resin that shipped with the softener. Definitely will be staying with this brand."
— Waldemar I. (5/5)
"This Resintech CNS10 Premium 10% Crosslinked Water Softener Resin is performing very well. My resin tanks started leaking from sun exposure and when I received the replacement tanks, I found green growth inside the tanks from the sun, therefore I replaced the resin. My Kinetico Softener has 2 tanks requiring a total of 1. 5 cuft. It was great to be able to order a 1. 0 and . 5 cuft bag."

"10% is the required resin by GE/Pentair ProElite refill, works perfect and now soft water again without going through the installation of a new unit (only available via dealer and can not order online)"
