I'm wanting to setup up a co2 system for my 15 gallon planted tank. I don't won't to do the co2 route again as it was very annoying. I also don't won't to go for a full pressurised system, I know this will be cheaper in the long run but I don't have the room or the money to spend up front. So I was wondering what co2 system would be the best, that's is still going to able to grow my plants well.
Thanks
