    CarbonDoser Electronic CO2 Regulator

    In Stock

    CarbonDoser Electronic CO2 Regulator Overview This product has forever changed the introduction of CO2 into an aquarium. Key Features Used for CO2 injection for a freshwater planted aquarium, or a Calcium reactor in a saltwater application. We guarantee that nowhere on this planet can you find a BETTER or MORE PRECISE regulator! This is OUR baby, we built it, tested it, and patented it. The problem of "dumping" is completely eliminated with this regulator. Dumping is always a problem with ALL OTHER regulators which utilize a needle valve. Simply because, a needle valve relies on the pressure on both sides of it for it's accuracy. So, even though you have it set at a certain "bubble rate", once the pressure in the cylinder (or the outside atmospheric pressure) changes, so will the amount of CO2 that passes through the needle valve. This is why it is physically impossible for any and ALL other regulators that rely on a needle valve to ever be consistent. Our regulator does not have a needle valve, but instead, it has an electronic valve that opens and closes in a fraction of a second, (each "opening and closing" equates to a bubble) and, due to the fact that it is "electronic" the "bubble rate" can NEVER change. Once it is set, it can never vary more than +/- 1/1,000=of a second. The low pressure gauge goes up to 45 lbs but it can be measured up to 60 lbs. Also included with CarbonDoser Free upgrade to John Guest push-in fitting CarbonDoser exclusive check valve Polyurethane tubing

This bubble counter is placed in the CO2 gas line, which minimizes visibility of CO2 equipment in the aquascape while still allowing the hobbyist to easily check CO2 output at any time. Compatible with 6 mm (1/4") - Standard Airline Tubing. Features Monitor rate of CO2 injection Minimizes the visibility of CO2 equipment in the aquarium Suitable for all aquarium sizes Simple and easy to use Compatible with 6mm (1/4") standard airline tubing Rinse glassware with warm water. Attach suction cups and desired tubing (Compatible with 6 mm (1/4") - Standard Airline Tubing) to the Bubble Counter. To attach tubing to glassware, wet the inside of the tubing with water at the attachment point and carefully slide tubing over glass. The use of other lubricants is not advisable as these usually make the tubing slide off of the glassware too easily. To avoid breakage when removing tubing, do not pull tubing off of glassware. Instead, cut tubing carefully along the attachment length to release the glassware. Mount your Bubble Counter upright (see diagram) using the suction cup(s) to the exterior of the aquarium. When removing or repositioning the diffuser, pull by the suction cup(s) rather than the glass to avoid breakage. Install check valve (not included) inline with tubing outside of the aquariumOnce securely mounted, turn on CO2. Observe bubble count and adjust CO2 to desired flow rate.
