Need help to reach Donald 1800 at Earthbox Forum

ACH!!!! HELP!!!

I've spent hours looking for one of the ingredients that someone who posts under the username Donald 1800 on the Earthbox Forum recommends highly. Does anyone know how to get in touch with Donald 1800?
OR
Do you know where to get 4X8AXC Coconut Shell Activated Carbon (particle size 1/4" to 1/8", acid washed for Ph neutrality and dust removal)?
OR
Is obtaining this product just a cruel joke?

Help me if you can please,

I did a google.com search for CSAC and found several places that sell it.

Thank you Kay. I also did the goole search and yahoo, etc. No one I found, and I spent many hours on the internet and $'s on long distance calls, had the acid washed. One company was willing to sell me 50 lbs of water washed at $2.25 per pound plus the cost of shipping. Way too expensive. Donald 1800, whom I finally did find, pays $60.00 for 50 lbs and it is acid washed.

I've decided to use the mix without the carbon this year and continue to seek a reasonable supplier for next.

Thanks for your input.
