at the moment, no... I have thought about it. (All I have in there is a couple of onion plants and a variety of Anubias.) I want to do a bit more research on the best CO2 system for my budget. I have also heard of people running successful planted tanks without CO2, so I need to start looking for plants that will do well without it as well...

Perhaps a DIY Co2? I bought one but I should have made my own. Not sure if they would work on a tank that big.

I found a really good link to a "recipe" for a DIY system. It looks simple enough, and should work with my tank size. I will probably get this started sometime this week, and then on the weekend, get some new plants :biggrin:
