Re: [APD] Carbonate shortage? -- or - Carbon carbn everywhere, even in books

Tom's post on this thread is a great summary on
carbon/carbonates and low tech tanks -- I prefer to call
them slow grow tanks because a bottle of gas and a
springloaded valve (regulator) doesn't seem very high as
tech goes.

Diana's book discusses a lot about plant chemistry/nutrient
needs, all in an extraordinarily accessible way. It's done
in the context of a slow grow tank but the basic principles
apply in a general way -- it's jsut that more light, more
CO2, more nutrients generally yields more plant growth in a
given period. If you're into aquatic gardening, I think you
owe it to your self to get a hold of a copy -- it isn't a
typical hobby book -- i.e., not a collection of postcard
photos with very little info -- instead it's full of info
with few pics. Many refer back to it often.

While I'm on the subject of books:
If an aquatic gardener bought only two books, I'd recommend
Diana's and Christel Kasselmann's _Aquatic Plants_. Almost
everyting else is just embellishment, a information
shortfall (compared to these), or too darn academic to
holds most folks interest.

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
