GFO

[Empress]

Can I refuse GFO? I'm going to take it off-line but I don't want to throw it away. I've only used it for a week and I'm pretty sure it still has lots of life left in it. Can I rinse it real good with fresh rodi and store it in an airtight glass jar so I can use it at another time? What do y'all think? Has anybody done this? Thanks.

I would rinse it in rodi water and the let it dry out. Keeping it in a sealed container might promote unwanted growth of mold or something else.

I'm following along as I am not sure on this

How much we talking about 1/2 cup or so?
Just don’t take the risk.
And there is no telling if it been used up or not.

You can store it in a glass jar. You will need to rinse it in ro/di water and dry it out. You want it to remain effective so make sure its not clumped after drying. I would toss it and buy new.

It's about 4 cups. But I'm pretty sure it's supposed to stay "moist" at all times even when it's not in use. It's not used up. I just used it to knock out some PO4. Now it's at zero and I'd like to save the GFO if I can. I think I'll give it a shot and see what happens. Thanks for the replies.

Gfo will bind Po4 and other compounds and ions. Sonthebsurface can become bound with so much we change it
So you basically want to chemicllly scrub it. Or “regenerate it.

If it’s not all completely used I would Justin dry it. It down not need to wet. I’d wager baking dry helps the crud fall off.

But here’s the regeneration process.
