GFO Reactor Problem

[gregzz4]

I always rinse mine in a mesh bag (probably 8gals of RO) over a bucket, and I run my outlet into my sock chamber to catch anything that may get past the foam

Not sure what happened in your case but I know that if mine were not rinsed well it could have happened to me
I used to get GFO back-siphoning into my return chamber when the reactor pump was turned off

I now have the TLF NPX filters between the GFO and sponges and pellets no longer escape

Only other thing that comes to mind is too much flow through the reactor ?
This will grind up the GFO, even if you rinsed it

That is one of the reasons I quit using GFO. It can back siphon, come out the outflow, clump together and all other kinds of mishaps. I have found Foz Down to be much easier to use and a lot cheaper. That is why I started to make it available for hobbyists.

Thanks guy

It has been working ok the way it was set up, then one day just had the problem. I do have a foam in it and not too much flow but did increase the amount last time I changed it but not by much maybe and inch more material.

Gregzz if you post some pics of your setup, gfo reactor
