The EcoPlus? Supreme Air Pumps are great for providing oxygen to hydroponic systems. In hydroponic applications, the use of an air pump with an air stone will oxygenate the water and increase the uptake of nutrients by the plant. The oxygen also strengthens the plant’s roots and helps prevents root rot. These air pumps are whisper quiet and built to be very durable in even the most extreme growing environments. Low power oilless motor. Use with EcoPlus? Check Valve #728400.
