Looking for a CO2 system for my 55 gallon i have T5 lights and now need CO2. I don't have crazy amount of money so i m looking for something that will be effective but within my price range. Was looking at Hydor Exclusive CO2 Green NRG System for Plant Aquarium its around 119 bucks but i m new to the whole CO2 setup. Plan on it being a very heavy planted tank. Also ferts wise liquid way to go or dry ferts in the long run? Thanks
