Black sand blasting media works, it cheap and easy to get. I mean stupid cheap compared to all these designer substrates. Try Home Hardware.

well, i went to lesco today and picked up a bag of soilmaster select charcoal for $11 even including tax. Awesome deal, if i do say so myself. I will put it in the tank this afternoon. I've heard that SMS will absorb nutrients from the water. Should i dose the substrate then so that it will give nutrients to the plants or does it not really matter?

How do you find distributors of the Colorquartz sand? Would love to find this, but have never been able to figure out where to get it.

I've got a Lesco by me. If I read this right, Soilmaster Select Charcoal is the same (or similar) to AquariumPlants.com substrate?

The manufacturer has a very good website with a special search for finding a distributor:

3m Colorquartz Black T-Grade

I'm trying to see the grain size range.
I'm looking for something in the 1-2mm range,
no more, no less...
