Im somewhat new to the planted aquarium and I would like to know if a non compressed C02 system is effective. And is it worth the money. I really wanted a much nicer one but I recently got laidoff from work and can no longer afford a high dollar system. tHE CHEAP ONE IS ONLY THIRTY DOLLARS AT MY LFS. Its made by nutrafin. If anyone has any other cheap alternatives Im open to any suggestions. I have a 29g tank with wisteria,Rotala Indica,java fern,DHC,crypt parva. thanks for your help
