I don't see why not. I've never used it personally.

You can put it were ever you want, depending on what type of flow your trying to achieve through it, for example slow to achieve anaerobic denitrification etc.

That’s why is comes in different shapes and sizes and can be cut up to fit were needed.

I was going to put some in my rear overflow chamber although I never got around to it, sort of drop in and forget, but I’ve recently changed to Seachem Matrix instead/as well.
