Re: [APD] Re: Peat in substrate
The peat is sort of an instant mulm for a new tank. Tom's
measurement method is more than accurate enough. It doesn't
require some precise amount. cover the glass is plenty --
the water will find it -- the roots will find it. Ski it if
you want, it won't ruin your tank. Add mulm if you have it
but peat will do if yo don't have mulm.
Folks have used pure Flourite, Onyx, Eco-complete with
great success -- even starting a new tank without mulm.
