The cycle time can be controlled by the timer, thus ensuring long-term yet accurate flow control. A balanced amount of carbon dioxide (CO2) plays a vital role in a planted aquarium and the building of coral reef skeletons. A very slow flow of CO2, sometimes only a couple of bubbles per minute, is desired for photosynthesis reaction in plants, and also for producing calcium carbonate (CaCO3) in corals. Previously a needle valve may be used. However the drawbacks are 1) difficult to adjust 2) drift of flow over time that requires frequent adjustment due to clog, vibration, change of pressure, temperature, etc. Power: 120v, 60Hz, 5WInlet Pressure: 21-71 Psi (1.5-5kg/cm2, or 0.15-0.5MPa)Special Tubing Included: 3/16" inner diameter, 6mm outer diameter, 1 foot longCycle time range : 0~1200 hoursWarranty: 1 year limited warranty ## Features - Long-term stable release of CO2, one bubble at a time - Timer adjustable from seconds to hours - Time saver for CO2 adjustment in planted aquarium and calcium reactor - Hassle-free as in needle valve not needed - Low-power, cool, no-heat operation ## Images ![Digital CO2 Doser - Image 1](https://m.media-amazon.com/images/I/614aX7vvgML.jpg) ![Digital CO2 Doser - Image 2](https://m.media-amazon.com/images/I/61WKkdmNyLL.jpg) ![Digital CO2 Doser - Image 3](https://m.media-amazon.com/images/I/51IrSovsavL.jpg) ![Digital CO2 Doser - Image 4](https://m.media-amazon.com/images/I/619GmF16tZL.jpg) ![Digital CO2 Doser - Image 5](https://m.media-amazon.com/images/I/61uFogDjoEL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars It's a fish saver ! *by H***O on Reviewed in the United States on August 22, 2016* I decided to give this co2 doser a try after a recommendation from a friend. The package arrived within one week. From the looks of the package, setup does not seem straightforward. After reading the instruction, I was able to set it up. I set the timer to 2 minutes as a starting point and yes !! It did bubble every two minutes. Then I used a PH meter to monitor the PH value in my calcium reactor. I tried to maintain a stable inlet water flow. After an hour, the PH value is stabilized. I think it works.The CO2 flow is low and very stable even after a month of use. That beats the unstable needle valve. Overall, I am very happy with this product. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Five Stars *by Y***S on Reviewed in the United States on October 25, 2017* Excelent product --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sk/products/93092428-digital-co2-doser](https://www.desertcart.sk/products/93092428-digital-co2-doser) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-04-22*
