Review: I was able to completely disassemble, thoroughly clean, and change the resin in my 12-yo Coolligan water softener in ~5 hours from A to Z. Required tools and materials: 1. The big blue funnel + a table spoon or whatever scoop you find 2. 1 bag of the resin being reviewed (1 cu ft) 3. 1 bag of gravel (15lbs) for water softeners. DO NOT FORGET TO WASH IT WITH FRESH CLEAN WATER before using! I do not recommend saving a few bucks and washing the old one, the time costs more. 4. Direct hands (TM) driver. Steps I did: 1. Closed water line to the water softener 2. Disconnected the resin tank, the salt tank and unscrewed the head from the resin tank 2a. Removed the inlet/outlet pipe from the tank (it's the only pipe inside the resin tank) 3. Drained as much water as possible using silicone tubes (my tank was dug ~2ft deep), this tank filled is heavy as my freaking life, otherwise 4. Dropped some large cloth to drain water, resin, and gravel (an old linen sheet that was used by my ex worked great!). You do not want to reuse the old gravel, just like you don't want to use sheets that were used with your ex:) 5. Thoroughly wash the resin tank, the salt tank, the pipe, and the head, i.e. everything that is possible to reach and clean 6. Sealed the top of the inlet/outlet pipe with painter's tape (to prevent particles getting in) 7. Inserted the tube vertically, centered and put the new _washed_ gravel in 8. Using a blue funnel for resing, patience, and time, shove the resin beads back into the tank 9. Assembled everything back, and put water back on. 10. ??? PROFIT!!! You'll notice that the water got softer, if: a. objective measurements say so b. dishwasher delivers better results (no white spots, crystal-clear glasses) c. harder to wash soap away while showering I did not experience any odors or bad smells, if only very little right after I changed the resin, it had gone in a few days completely. But I bet, I would never have noticed it if I hadn't known that I changed something in my system. Yes, this product is great. Yes, I spent ~5-6 hours of my life. Yes, I got satisfaction while working on this project. And yes, I saved about $1500, paying about 150-200 total. I highly recommend this product and the brand in particular.
Review: Worked exactly as expected and the water was soft the same day after the first recharge cycle

## Questions & Answers

**Q: what is the difference with 8% verses 10% cross linked resin?**
A: The 10% resin has a harder shell than the 8% making it more chlorine resistance. So 10% would last longer on a chlorinated water supply. 
The folks at Aplus Water.

**Q: Will this resin work in a kinetico k60 system?**
A: Yes it should do the trick to restore your softener. I installed this resin in my system three years ago and it has been working like new ever since.

**Q: Will this work in a spring mate by brauch water conditioning co.?  it's about 28 yrs. old.**
A: This is standard mesh softening resin that should work in any water softener. If you have any doubts, be sure to check with the manufacturer of your water softener brand. 
The Folks at APlus Water LLC

**Q: A lot of iron where I am at. Will this help with keeping iron rust orange from coming through**
A: I assume your water has 1-10 PPM iron.  Most likely 2-3 PPM Iron.  Have your water tested for free so you know what your working with.  If more than 10 PPM than your need a special industrial system. I have a iron filter. Uses water to clean the coconut shell media. Iron filter about $1,200.00. Other medias are available based on your water. Other than that you can use your water soften to remove the iron. Hopefully you water softener can handle iron. If not then you might want a Iron breaker water soften for about $2,200.00. Or as I have a Whirlpool 33,000 Grain Water Softener about $400.00. Lastly many other new models are out there. Do your research so you don't buy options/equipment you don't need.
