With things in this hobby being not exactly cheap I will ALWAYS recommend sugar and yeast DIY CO2 to those inclined to try CO2 injection for the first time. It will give you the same results as the more expensive setups (after all it's the same gas, the same molecule). It's a lot more work that's true, but its virtually free to try. I would've never bought a cylinder if I didn't had the chance to try it for free first and I'm glad I did!

It all started here and was certainly a nice (although sometimes bumpy) ride :D

If you look for nymphaea amazonum  on Google Images you won't find more than a couple pics of it inside a fish tank, and even the Wikipedia article has only illustrations, so I thought I would put a couple more online just for the sake of it. Initially I bought it because it was half the price of Nymphaea Zenkeri, whose color and texture of the leaves I like very much. It already has a couple floating pads which I found quite charming.
