Is this stuff pretty good?

Yes it is, and Dr. and Foster has the 4L for 16.99 that's 50% off

Sigh, of course I bought at full price just a month ago -_-
I can always use more, though! Thanks for the heads-up!

How does this stack up against bio rings? I used the Matrix in a 5 gal, but would it be just as effective as bio rings in a 30 gal?

I personally prefer matrix or pumice to bio rings. TBH I was only given matrix one time and otherwise use bags of garden pumice :/

I use it in all my canister filters and have zero ammonia and nitrites.
