Carbon is confusing

Usually I get tricky :D Send it American Norit the largest GAC manufacture in the world. BS them you do not have a clue what this stuff is and ask, IS it bitum, lignite, peat is, regenerated, is it crap, what is the Iodine# Molasses # ????? Someone says this stuff has 1500m^ 2 TSA and you think it is BS. Do yon have a GAC like this stuff ? Is it your GAC ?

Usually you just send it and they test for free, at least they use to for me. I can't test anything anymore. I gave all my stuff to Randy Holmes-Farley. There is no one in this hobby currently that can properly test GAC for the usually listed parameters. I have the methods book for doing it but you need lots of lab equipment.

Try the PO4 glass trick with some and see what you get. Find someone with a micrometer and see what diameter it is. If it is 0.8 mm it is American Norit "Row" GAC. If it is 1.5 mm it is more than likely that stuff on the link I gave. Take some RO/DI water and adjust the pH to 7 and dump some in, don't rinse it first and see if the pH changes up or down

I figured someone would ask that :lol: I just should have posted it.

First, it deals with something called Break Through Flow Point, which I'm not going to get into. This one has one of the best, if not the best in the hobby. In short, water goes in the bottom and comes out the top. So all of the water is pulled up form the bottom to the top. Many canisters have both the inlet and outlet at the top, which cause water channeling, meaning some of the water by-passes/may by-pass the media. Most of these canisters have lower BTFP. If you took some of these other canisters and filled the baskets with cement, water will still flow through them. In these Eheim's it will be dead stopped. In the Ehiem's you just put a screen/sponge in the bottom and one at the top and leave the GAC in there by itself loose, no bag, no baskets. The water HAS to flow through the GAC.

An example of a filter with the worst BTFP is one of those hang-on the back with the compartment dividers. BTFP deals with the filter designs and how water by-passes the media. At 100% BTFP there is no by-passing. Some filter designs are way above this value and are not efficient at all. Some, like the Ehiem, can run much higher than their BTFT and still be very efficient. If a filter has a 100 gal /hr rating and its BTFP is 100, then it should not exceed 100 gals / hr. A crappy hang-on the back may have a flow rate of 200 gal /hr but is BTFP is 60 gal /hr which is 333% above its BTFP.

Bob I just had a 3 hr phone conversation with Jesse from Elos to help them clear up some of their remarks on thier website. He is sending me some GAC as he wants to know what it is also ;) At least I will know if it is ROW or not. It sounds like it is :D That will be 3 companies in the last couple of months now selling ROW. It only took me like 15 years to get someone to sell it :lol:
 
Boomer-
so what about the two little fishies reactor? Also flows upwards, no need for a bag....

BTW, wife is back in town with the camera, will try and take some pics of Eric's carbon.

So Boomer...can I put away the micrometer for now:D Just kiddin...can't wait to hear what you think after checking out the Elos Carbon.
 
Mat that reactor is for GFO but could be used for carbon also and should work well. That would be another good means and forgot about it.

Bob and Barrier GAC is on the way :D


Tracy, ROW is an old name used by American Norit, the worlds largest manufacture of GAC. They now have dropped the ROW name and use other names like ROX, as they expanded these carbons to 4 different types IIRC. I do not know what they mean by ROW, ROY or ROX. GAC = Granular Activated Carbon.

OK so when you say three companies are now selling ROW- you mean they are marketing a carbon from a specific manufacturer? Were you refering to a specific formula they sell? I checked out the Norit website and it looked like the Darco 4x12 is a good candidate- Is that the one that Elos could be using? What were the other two that you thought were now using ROW GAC- was it Warner ultra(the new one)? Who was the third? Thanks for all the great info.

Cheers,
Tracy
 
Draco

No, look for ROX .8 on the Norit website. Draco 4 x 12 is just an avg lignite GAC and is not a extrude pellet carbon like ROX. If one is to choose Draco then you want the Draco LI 10-20 or 20-40. I might add that Hydrodraco lignite 3000 or 4000 is even better. They also make a good Bitum GAC 1240 plus but not as good as lignite. This sufff would be better than anything on my list except the filterguys, Warner and TLF. The Bitum, GAC 1240 plus, would be simlair to Black Diamond or the Eric's stuff only this stuff is acid washed. And you WANT acid washed GAC if you can get. Norit GAC 1240 is about the same or the same as Black Diamond or the Eric stuff and is not acid washed. Two GAC's that are exactly the same and on is acid washed and one is not the acid washed, the acid washed is ALWAYS the better GAC.

Yes the Warner Marine Ultra is the one.

awesome dood, i can't wait :D .

I'm really happy to hear that the Elos company is willing to send you some GAC to check it out :D ..... seriously i can't wait to hear the news :D .
 
I have the carbon now but do not have a data sheet yet. It looks like some nice stuff. I have had a number of phone conversations with Jesse from Elosusa. He is going to send me some data on it which will tell me more. It is an odd looking GAC and has a slight grayish tinge to it. I do not think it is Norit but some kind of copy in a bitum type rather than peat type.
