Can I reuse GFO that isn't exhausted?

[TWYOUNG]

After treating my tank for ONE DAY with gfo in a reactor my phosphate dropped from 0.48 to 0.15. Due to a history of dinoflagellate issues I'm not comfortable going any lower at this time. I took the reactor core out and placed it in RO water to rinse. Can I save/store this for future use and if so should I leave it in water or let it dry out?
Side note: I know it's still good bc I've tested the reactor output water. Yesterday the inflowing phosphate level of 0.48 was reduced to 0.07. Today the tank water level of 0.15 was being reduced to 0.03 on the output side.

I would have just reduced the flow to a tiny trickle and left it in place. Even turned it off completely.

I'm not sure what effect RO water may have on ferric oxide.

Thanks. I'm pretty sure the media suggested rinsing in tank or RO water. It's a dual reactor so I can't change the flow to the gfo without also changing the carbon. Next time I believe I'll be using less gfo.

Yes, you can reuse it, but rinse it well before storage, and again when you want to use it.

Should I try and dry it somehow? I've heard the reason to "tumble" it in reactors is to keep it from solidifying.

The solidification is from calcium carbonate precipitating in it. That won’t happen after to/di rinsing.
