DI Resin?

[Bak2theReef]

I bought some DI Resin (3 lbs) 3 years ago and have had it in storage for the last 2 years in a zip lock bag. It is still moist and doesn't seem to have darkened much in color. Is it any good now? Can I recharge it?

I would start all over. But that's just my opinion. I wouldn't even try using it.

Overtime when the resin is exposed to air the resin loses its ability to pull the charges out of the water. the moist felling is a protective coating to protect the resin from picking up charges from the moister in the air. I think it is some sort of non polar oil base coating but I’m not sure exactly. and I wouldn't trust a Ziploc bag to keep the air out or to prevent the resin coating from drying out. I use a vacuum bag sealer to store my leftover resin.

I would just toss it out and buy new stuff.

Thanks for the input. I will start over.

If you have a TDS meter on your output, wouldn't it be worth trying and seeing what the resulting water registers?
