  Soil mix - grit - aquarium gravel?

I've often wondered about the commercially available aquarium gravel
- not the colored kind. See photo at:

I realize it lacks the uniformity of other products, but it should be
quite inert.

Any comments?

I certainly wouldn't have any problem using the gravel you mentioned, Don.
I don't think the inconsistency
of grain size in this would be a big deal as long as it was within a certain
screened size, not too small or large.
But I wonder about cost of this stuff. And again, I still have my doubts as
appropriate for Aroids, other than
perhaps for seeds, seedlings, small pots.

Don,

Why pay retail price for a hobby material like aquarium gravel when you
can

I'm sure you're right about the cost, Ray, except that I have a 30
gal. can full of the stuff in my basement from my aquarium hobby
days! Besides, I'd have to go 30 miles outside of Milwaukee to find
a farm store selling chicken grit. My main concern was just to make
sure that there was no harm in using the stuff.

Don,

I'd like to interject one caveat with regard to using "aquarium"
or other graded sands/ gravel... Rinse them very well before use!

It's not uncommon for some of these materials to have a high salt
content when new if they originated from coastal deposits or mines
(even ancient sea beds... ). Such is the case where I live, anyway.

I have personally used graded sand/ aquarium gravel* in my aroid
mixes, but no longer. I find it's nowhere near as effective as small
3/8" clean lava rock or pumice for increasing porosity. At this
point (for me) the only value added in using graded sand is in adding
ballast to the pot for otherwise top-heavy plants.
