The link seems to be dead. IDK, but I'd be afraid to use any type of coal or coal byproduct. Isn't there a chance of harmful substances leeching out of coal, like petroleum or hydrocarbon elements?
neonfish3 said:I've also been using Black Beauty for about a year now. I love the look of it, and I haven't noticed any changes in Kh/GH/Ph. Mine looks a little finer then yours. Iv'e herd that plant roots can be cut by the sharp edges, but I haven't noticed it my self. Also like you said it does get dirty rather quickly. I have a powerhead blowing lightly across it to help.
I found this info in my research :

I put 100 lbs of Black Diamond (same thing, different brand from Tractor Supply) in my 220, cost me less than one 20 lb bag of black aquarium sand from Petco.
just wanted to throw this :: i wouldn't think there'd be too mu... been used for years with no problems. Mark
There are 8 juvie Synodontis lucipinnis and at least a dozen BN (handful of nearly adults and a number of fry that hitchiked inside a resin ornament) in the tank, as well as a couple of Tang spiney eels. I'll be adding a goby cichlid soon, so we'll see how the sandsifters like it.Do you use it with catfish?

One thing I did notice when rinsing it was a thin film of oil on the water surface in the bucket. The water was considerably less cloudy than with sand or fine-grade gravel though, and rinsed clear much more quickly and easily.
