    So your planted tank has the best lighting available, and your plants still won't grow? What could be going on? Most likely, your tank is not producing enough CO2 to keep up with your plants' needs. A CO2 controller from Milwaukee can help. This system can be programmed to deliver a specific dosage of CO2 at times you control, with the use of a CO2 regulator with solenoid (sold separately)
    Featuring an LED alarm system to alert you when errors are detected, as well as a built-in pH reader, since pH is closely related to your CO2 level. A 9v battery, calibration solution and instruction manual are included. Accurate to + 0.2 pH.

    Wrong picture, wrong description 6/24/2014

    looks NOTHING like the picture. It also does not control CO2, as the description says. It controls pH with a buffer solution.
