Anyone know where to get the chemicals to recharge DI resin? And any tips you have on how to do it would be appreciated.

hardware store for the HCL, grocery store for the Lye (NaOH). There is an article about recharging, shouldn't be hard to find.

Muriatic acid at Revy. Lye at Safeway. Instructions are at http://www.reefs.org/library/article...mann_chem.html

I have recharged many times, I still use a 50% mixture of Muriatic Acid and water even though the stuff bought locally is 20 baume. After recharging run lot's of water through it, and when in use run it for a couple of minutes to get rid of the fishy smell. Don't know why it is but it seems to be a byproduct of the recharging process. The smell eventually goes away

Any more Q's fire away.

I'm curious as to what recharging DI really means? I recently purchased what I thought was new DI resin from Jayson (It was a large bottle of Sand like stuff), to re-load into my RO/DI machine's cannister. The entire jar was around $30 and should last me over a year. Is this the same as re-charging?

Nope, that would be replacing the old resin with new resin.

Recharging is when you take old, expired resin, throw a bunch of chemicals at it and make it new again.

Well I did my recharging last night. Very long process, but worth it in the long run. My chemicals cost me $10, plus $20 for some used DI resin. Ive now got enough separated resin for about 5 refils. And when it comes time to recharge again, Ive already got the leftover chemicals to do it.
Its well worth it, especialy when your paying $30-$45 a pop for a brand new DI cartridge.

Hey Chris, Will the recharged beads still change color when exhausted?
