Building a freshwater vivarium?

[RhacHead]

and CO2 supplementation costs $$$$.

A good friend of mine had a nice well planted aquarium.It ended up costing him to much in CO2 tabs to keep the plants thriving so he broke it down.That is something you will want to consider. Not only will you have to put time in to maintain and the cost of setting it up but also what will it cost to keep it running.
