Basic AQUATEK CO2 Regulator with COOL TOUCH SOLENOID
Aquarium:Perfect for calcium reactor and Freshwater Plant CO2 injection applications. Compatible with most CO2 atomizer and diffuser. Calcium Reactors and CO2 fertilization require far more precision in their dosing.  Our Deluxe CO2 Regulator with solenoid is the best we've seen.  Unit comes with dual gauges each with dual reading of both psi & kg/cm.  Left gauge meters tank capacity and right gauge output pressure.               Green house and Hydroponics:Carbon dioxide is one of the essential ingredients in green plant growth and is a primary environmental factor in greenhouses. CO2 enrichment at 2, 3 or four times natural concentration will cause plants to grow faster and improve plant will quality.The reason you will get more rapid and efficient growth and better plant quality with a higher CO2 level is because plants must absorb CO2 in combination with water, soil nutrients and sunlight which produces sugars which are vital for growth. If any of these elements are missing or low, plant growth will be retarded. When CO2 is increased to over 1000 ppm it results in higher production and plant quality.CO2 fertilization require far more precision in their dosing.  Our Deluxe CO2 Regulator with solenoid is the best we've seen.  Unit comes with dual gauges each with dual reading of both psi & kg/cm.  Left gauge meters tank capacity and right gauge output pressure. With its fine tuning capabilities and electronic regulation, this CO2 Regulator meets the highest industry quality standard.
