I may try to breed cherry barbs, and this is recomended.
What is it, and where can I buy it?

Save your money.  You don't NEED it to breed barbs.

If you want to make your own, just get an old used coffee pot and run PEAT thru it. That will make a nice dark Peat Extract.

Or just use peat in your filter.
