How much leonardite?

I originally posted this question in the low tech forum since the tank is going to be low tech, however, I'm thinking it might be better suited here.

I'm gonna be setting up a 55G tank following Tom Barr's advice as found here: . However, I'm a little confused on how much leonardite (ie: Diamond Black from General Hydroponics) I should be using. In post #14 ( he mentions to use about 3/4" of leonardite, however, in post #52 ( he mentions to use less than 1/2" ... that's almost half the amount recommended in the other post.

So I'm wondering, should I get about 6 pounds of Diamond Black (ie: around 3/8" coverage on a 55G 12"X48" tank) or 12 pounds of it (ie: around 3/4" coverage)?

Thanks for any recommendations,

I would PM Barada, one of the mods. He has used this stuff instead of peat in his 120 gallon, I believe.
