How to make Blackwater extract [was Re: New subscriber to the apisto@aquaria.net mailing list.]

Absolutely, however in Austin, the $6 borelli is sort of a common occurance.
It is kind of nice living near Amazonia here in Austin.  They've got access
to or carry virtually every cichlid on the planet.

I use a trick that was acredited to a guy named Oleg on the killifish
mailing list.  The suggestion is to take a large bucket & put in an
undergravel plate & uplift tube.  Add a bunch of water & boiled peat.
using an air pump, keep the mixture in constant motion, and you have very
cheap "blackwater extract".  If you want to really get the tank dark, use
a sponge filter & just dump in a lot of boiled peat.  That takes the tanks
to a blackwater environment in 2 days.  The common pH range that I'd take
it to was 6.4-6.8 depending on the particular water change & how much
blackwater I used.
