I would appreciate any advice on purchasing and setting up a CO2 system for a 90 gallon planted aquarium. The Bioplast ProfiStar system sold by Arizona Gardens looks good. But I'm not sure where to get a solenoid and controller and how they would connect to the Bioplast system. Would it be better to assemble a system from scratch as George Booth suggests in his article at TheKrib.
