OK, I'm now a self proclaimed expert on granular activated carbon (GAC) 
... so here is the deal:
I found the ultimate carbon! I found a supplier who supplies many of the aquarium resellers. The GAC is made from lignite coal which is the undisputable over-achiever of the GAC market. Read this test data: http://www.pets-warehouse.com/carbon.htm, you will see the GAC made from lignite coal is far superior to other GACs available. Pay attention to the first 2 graphs.
It has a low Iodine number of 500 which is a measurement of the microporosity. It is very difficult to find this low of a value. The following link suggest an Iodine number less than 600: http://www.hallman.org/filter/gac.html. Matrix Carbon by Seachem has a Iodine number >1000: http://www.seachem.com/products/product ... arbon.html.
They do not state the Molasses number, but claim it to be very high. I can supply a PDF data sheet for this material if anyone wants.
The GAC is sold in 40 pound bags for $2.88/lb + shipping (no tax). If we order a pallet of 30 bags (hello Josh!), then the price is $1.44/lb (half!). I checked http://www.premiumaquatics.com for this same quality carbon and found a 4 lb bag for $29.95 ($7.49/lb OMG!): http://www.premiumaquatics.com/Merchant ... y_Code=TLF!
OK, that's it, let me know your quantity and we'll see what we have.

I currently have the following interested parties:
Scott --> 5 lbs
Xster --> 80 lbs
Salt'n'Lime --> 20 lbs
reeferpuffer --> 40 lbs
ShagMan --> 20 lbs
That's a little more than 4 bags. Between this and the Ferric Hydroxide, I can not 'front' the money, so I am implementing a new policy...
Terms and Conditions of Purchase:
1) I have a paypal account that you can send me money 'up front' to make the purchase. I will order this stuff on 12:00 PM on Monday, March 29. If I have money in my paypal account from you or if you have dropped off the funds at my house, then you will have your carbon. The cost is $2.88/lb plus shipping cost & paypal fees (unfortunately I am charged 2.9% + $0.30 per transaction, so I'm going to pass that cost on to you guys). I do not know the exact shipping charges so let's assume $3.25/lb shipped. I will refund/collect the difference when you pick-up the GAC.

2) No refunds!
3) You must pick up your own GAC at my home or any of the MBRK meetings I am attending. Make sure you include your name, phone number, and MBRK username.
4) If there is a little left over... you guys will help me find someone to buy it!
Why do I do this? I'm glad you asked! I do not turn a profit off of this in any way, shape, or form. I too like a good cheap source of maintenance supplies.

We are looking good for an order to go out on Friday. I will have very little left over if the following people will contact me regarding money:
Phisher: 3lbs GFH x $5.50 <-- Just send me a PM confirming you want it. I can cover this small cash.
ReefPuffer: 40 lbs GAC x $3.25 <-- I need this before I order! Contact me.
Salt'n'Lime: 20 lbs GAC x $3.25 + 5 lbs GFH x $5.50 <-- Oh ya! Need this too.
Kevin: 20 lbs GAC x $3.25 <-- Just swing by the house in the next day or two.
Total Order
GAC: 200 lbs
GFH: 105 lbs
Wow!
After the above listed people, everyone who has sent me money, and some I've reserved for Josh (5 gal hex tank), I will have the following to "dump off" to the first available:
GAC: 1 lb
GFH: 5 lbs
If anyone not listed above or who has already paid wants it, contact me!
