    Am I correct in my thinking that Black Diamond blasting sand, which I have read about being used as a substrate by some people, is not the same as Diamond Black aka leonardite recommended by Tom as a carbon source?


    I have a 29-gal cube tank which currently has a quartz gravel substrate with grains that are about 1/4 inch. In the spring I will be switching the substrate to pool filter sand. I'm thinking of doing a thin layer of leonardite to provide carbon for the plants without having to do the DIY CO2 yeast thing again. By the way, where does one get leonardite?

    That's correct, they are two completely different things. Leonardite has been hard to find lately, but there's a product made by Down to Earth called Granular Humic Acids. According to the MSDS sheet it's pure oxidized lignite which is leonardite according to Wikipedia. It's pretty cheaply priced too which is nice.


    Thanks,
