The first step to a beautiful planted tank is good lighting. The second is providing the proper amount of CO2 for your plants to utilize. Attach this CO2 Pressure Regulator to your own tank of CO2 and you can read the exact pressure and output of CO2 into your tank. Professional construction includes solenoid diaphragm valve with 1.5 meter power cable and bubble counter including micro adjustment needle valve.
This is a no frills regulator that does everything you need for a basic set up. Bubble counter works great with the needle valve and the solenoid turns unit on when your lights come on. Make sure to use the plastic insert that goes in between tank and regulator, they even give you a spare.
