As topic..

I stumbled over a bag of Lignite in an old aquarium shop.

What is it for?

Substrate?

activated carbon?

It says only:

Lignite
Watts, Blake, Bearne & Co PLC
Newton, abbot, Devon
UK Origin.

Anyone?

Lignite is immature coal. As for what it's used for, I think I saw an article a while back which suggested using lignite (diamond black or something like that) similar to laterite, under the substrate.

I've never tried leonardite... or anyother bottom layer substrate.. apart from good old peat, and Tropica's aquacare substrate of course.

I'll keep it in the garage .. :)
