Has anyone attempted to recharge GFO?

[nickyblase]

I found a few interesting links/articles to it, and while the thought of using Lye is a little daunting, it sounds like it is not all that difficult.

Here is what I dug up today when I did a Google search. One was a thread on RC with Randy's input, and another was a somewhat shortened version from a reef club in WI.

I have never done it myself, but I am going to start doing it soon. Skiptons sells (or at least used to) regenerated GFO, and I have also been told (but never verified) that what Bulk Reef Supply sells is regenerated GFO from large water treatment plants.
