Water Softener Resin Media Replacement - 1/2 Cubic Foot (CuFt) | 100% Ion Exchange High Quality Premium Cation | 16,000 Grain Capacity | NSF Certified (MED-CAT-025/2)

This resin does exactly what it's supposed to do - it exchanges sodium ions for calcium and magnesium ions. This is the basis by which water softeners work! As the negatively charged resin grabs positively charged ions (cations) like calcium and magnesium, it releases (or exchanges) positively charged sodium ions. When the resin can hold no more calcium and magnesium, it's time to recharge with a very high concentration of salt solution (brine). This knocks off the calcium and magnesium ions that then get flushed away and are replaced by the sodium ions, and the process starts again. So yes, TDS can remain the same or even INCREASE during this exchange process and this resin worked wonderfully to bring my 16,000 grain portable softener back to life.

It was very easy to install after getting the old out of what I call the bell. Getting rid of the old and adding the new has made showering in our 40 foot fifth wheel very nice.

Refurbished my softener cylinder with this resin media and other components (rings, filter basket and draw pipe) Packed in this resin and it went flawlessly. Saved my softener and and getting wonderfully soft water again. Well water FULL of iron, Nickel, Magnesium, Manganese.. Super hardness. All handled effectively by these new beads. Totally worth it.

I purchased 1/2 CuFt of resin to increase the capacity of an underfilled softener resin tank. Shipment was quick, and there was no damage to the bags containing the resin, which has identical appearance to the resin already in the tank. The only reason for less than 5 stars was that the price would have been lower elsewhere, but I needed it quickly (and it was delivered quickly).Note that when adding new resin, a small amount of leaching- fractured beads/residue- is normal and to be expected when water is first passed through the tank. After connecting the softener tank, I ran water from a faucet near the connection. The water started discolored (gold/tan), but after about 5 gallons ran completely clear. Again, this initial discoloration is to be expected with fresh resin, and I cannot say whether it was from the resin I bought here, or the resin (also fresh) already in the tank. I anticipate no problems with the resin.

Use this for my RO water for my saltwater aquarium works great

Our full-time fifth wheel in the Arizona desert will have access to clean water for on-the-go needs. Immediate results are expected.

Maybe it's on me, but pretty sure it's the product. Shouldve guessed when it all said water SOFTENER resins.The 1st pic I have 3 stages for automotive use. I built it, im no stranger to this stuff. And even reversed them for trickle down top to bottom vice versa etc for testing. (4.5x10 vessels)1st step is activated charcoal fine mediaStage 2 is cation media (THIS PRODUCT)stage 3 is anion resinStarted off washing all the media with pure 0 tds water. Installed filters with compressed media. 10.1 gpm 161ppm at the hose. Tested first 5 gallons and it was at 9.1gpm 159ppm. Did this for 30 gallons at .5 gpm no drop in ppm. Stays around 141-151.Then tested each EACH individual vessel.Carbon drops 20ppm post filter, Cation (this brand) RAISED 15ppm.Anion -20ppm.Then I came inside and tested DROP BY DROP after washing fresh 4oz of beads with distilled 0ppm water. Then tested distilled water thru media adding 16ppm. Then went to tap. See the pics, I did drop by drop for over an hour and I was not happy.I'm going back to mixed bed resins, this wasted 2 days thinking it was me messing this up. Nope

Watched a youtube on how to change it in an on-the-go softener that is 14 years old. Was easy to do and the water is now much softer and was a lot cheaper than buying a new one.
