The electronic CO2 regulator from AquariumPlants.com is a very unique apparatus uniquely suited to ultra precise control of CO2 gas. The electronic CO2 reg can dispense the precious plant-growing and aragonite-dissolving substance at a rate from 0.1 to 10 seconds per bubble. The rheostat control know is somewhat counterintuitive to use because turning the knob in a clockwise direction will increase the length of time between bubbles so cranking it to eleven will actually reduce your CO2 release rate. If you’ve ever wanted to pull you hair out because you found it difficult adjusting a consistent bubble rate, the elctronic CO2 regulator should be just the fix. AquariumPlants.com claims that this electronic device was built completely in house, and we believe them, but at first glance we totally believed this was an OEM product. The complete electronic CO2 regulator from AquariumPlants.com is $189 or just $149 for the electronic control box to add on to your existing reg with 1/8 or 1/4″ brass fittings. There is also an Uber-precise version with an 8 digit LCD display which will run a $100 more than the complete regulator set at $289.The LCD display is a bubble-odometer so it keeps track of how many bubbles have been released and the counter is user resettable. Also, when used with high pressure and turned to maximum flowrate, both versions of the E-regulator can release a maximum of 4 bubbles per second.

FEATURES:
-fully automatic
-fully electronic
-perfectly accurate (from 4 bubbles per second (240 per minute) down to 1 bubble per 10 seconds. (Count can NEVER vary more than 1/1000th of a second!)
-fully adjustable: you can adjust the “bubbles per second” (or “seconds per bubble”) & size of the bubble (very tiny bubbles all the way up to very large bubbles)
-NO bubble counter (you count “the LED light flashes instead of bubbles through a bubble counter)
-NO solenoid (that overheats and eventually fails)
-No needle valve (the “timing of the “bubbles” is fully electronic)
-Low voltage (12 volts & only draws .5 amps)
-Built in (internal) check valve
-3 year bumper to bumper warranty
-Yes, it can be controlled with all pH controllers (just like others with a solenoid…just plug it in to your pH controller)
-Available with optional LCD 8 digit resettable counter (has “backup” battery, will not lose it’s count)
-Now available: “Just the Box”… Many customers currently have a “very expensive” regulator body, with poor quality needle valves/bubble counters/solenoids, so, we are now offering the “electronic control box” separately to use with your existing reg body. They utilize a 1/4″ or 1/8″ NPT thread size. (contact us if you wish to send your reg body and have us assemble it and test it for you, this service is only $10, and well worth it)
