I am stiil researching co2 sources for my 55 gallon planted aquarium with fish. I just bought a Turbo CO2 Bio System with powerhead(not open yet...). It is advertized for 42 gallon aquariums. I am trying to avoid a pressurize system. I want really good results. Will this sytem work well (the sales person claims excellent results). I also want to know if anyone has had good luck with the newer carbon plates/electrolysis systems... they seem reasonable and makes sense, at least on paper?
