Re: [APD] Re: Carbonate shortage?
I'll note an exception to the no-water change policy.
Anyway, very few water changes. Diana Walstad, in her book,
_Ecology of the Planted Aquarium_ describes in very good
detail how to set up an aquarium without high light levels
and added CO2 and only small additions of water to make up
for evaporation. As I recall, she changes the water maybe
once every few months.
A slow grow tank set up, such as Diana describes, can make
for a very nice, very low maintenance planted aquairum.

Tired of filling that aquarium all the way to the top? Ready to try something a little different? Think less water, more options. Think paludarium.
Aquarium Design Group's Mike Senske raised paludariums to a whole other level. SEE Senske paludariums at
