Re: [APD] Water Hardness and PH

[Michael Leong <fluidcloud at gmail_com>]

Echinodorus are only submerged part of the time in the wild. Some
never get totally submerged at all. For this reason, they have
developed in a way that
they are dependent to a large extent on root feeding. Put fertillizers
in your substract as well if you want Echinodorus to do well in a
tank.
