O2 Grow - Model 2040 -40 Gallon Capacity - 20 Gallons per Emitter
The 2040 unit is our most popular model! This unit gives you the option of using both emitters in a 40 gallon reservoir or splitting them up into two different 20 gallon reservoirs. Either way, this unit is designed for use in 30-50 gallon barrels. Similar to our other units, this 2040 allows you to place both emitters in one reservoir or you can split them into two different reservoirs. The unit makes no noise and will not heat your water. Whether you have 20-40 gallons, it only takes a hour or less to super oxygenate your nutrient water.

O2 Grow units are basically plug and play. Simply remove the unit from the package, connect the emitter to the power supply and then connect the power supply to the control box. Then, plug the power supply into the wall outlet. You should see a green light on the control box. The unit is now ready and the emitter can be placed into water. Once the emitter comes in contact with the water or the nutrient solution, this will complete the electronic circuit and the emitter will begin emitting bubbles.
If you do not see bubbles, make sure that your water has some electrolyte in it. If you are using reverse osmosis water or purified water, you will need to add some nutrient to make the emitters work.
The best method for oxygenating your water is to run the unit just before watering your plants, or on a timed cycle to boost oxygen if you are growing in a hydroponic method.
O2 Grow Emitters will require cleaning from time to time. Over time, the Emitter may get a calcium build up from the water. A quick rinse in muriatic acid will remove the build up from the screens. Properly maintaining your screens will prolong the life of the Emitter.
