Chemi-Pure is mostly carbon. The reason behind the meshbag is so you ca beat on it and expose new surface areas. Rinsing it will help but it will not last as long
dagamad
personally use the TLF hydrocarbon
That is a great carbon actually one of the first on my list but is way over priced and is the same thing a AP GAC, which is cheaper. It is a Lignite based GAC and is better for water application due to pore structure and molasses #. The reason I do not recommend these as much is that they have more dust, so it is not as user friendly and people whine about that
It is made buy American Norit .

Well, these ROWA people do not know much about GAC. I just about fell out of my chair when I read this;
Many low cost carbon products on the market place are washed in phosphoric acid as a final stage of their preparation and can release high levels of Phosphate into the water. Rowa Carbon Contains extremely low levels of Phosphate.
There is a BIG reason for acid washing GAC. It is AW GAC that is the most expensive not cheapest and the best. I wonder what your ash content is with that stuff, must be through the roof.
have to say it crackles more then any other carbon I have tried in the past
Gee, I wonder why that is
Called trapped air you do not want that. Put some regular water in a container, now add the GAC. Ooop's I forgot put you pH probe in the container first and tell me what happens to the meter reading ( some GAC is treated with CO2 ) Big reason to always rinse GAC.
Viny
Kent for me
This is kind large pelletized GAC, it is designed for VPC (Vapor Phase Carbon) and not LPC ( Liquid Phase) it is made buy Calgon. Yes, it will work fine but is a poor choice. I told Jack Kent that when he decide to buy/sell it years ago but never listened.

SeaChem Matix or Marinelands Black Diamond
You are on the ball
Stony
As far as I know the black diamond is one of the only REAL carbons
All carbons are REAL carbons are GAC, no matter what they are made of and Lignite is the best for our application, well, actually PAC is. Only charcoal carbon is the fake one and allot of LFS bulk buy this crap. You can tell what it is as it is hard and shinny. It is often anthracite coal. It is not activated at all. Its capacity is about 10 % that of GAC
