Carbon GFO question

[tritan]

I am about to run a carbon & gfo probably once in a while for my tank. My question is what do you do while you are not running it? Is it okay to leave it sit with tank water in it for weeks stagnant? Im curious what people that run it at times do.

Either run it all the time or take it out when not running it.
I run both 24/7.

+1 Dennis...I wouldn't let it sit stagnant for too long.

The GFO reactor turns into a stink bomb if you let it sit stagnant with water for several days.
You do not want that gunk flushing back into your tank when you start it up again.
