The Aquatic Terrarium Kit is complete, nothing else to buy. You need to supply table sugar is all. It comes with two Aldrovanda, they grow and spread fast. It takes about 10 minutes to completely setup. Very easy and cheap to maintain. You will need a small pouch of yeast once a month or so, the first pack is included with the kit. All you need to do is add fertilizer once a month and re-charge the Co2 generator once a week. The aquatic critters should keep algae under control, if not a partial water change usually does the trick.

You can add a couple trumpet snails too if you want. You can drill a hole in the aquatic terrarium to insert the Co2 hose through if you prefer to stealth it in.
