Designed for North American CO2 cylinders, it ensures safe, customizable, and energy-efficient CO2 delivery for one or two aquariums. ## Description desertcart.com : FZONE Pro Series Aquarium Dual Stage CO2 Regulator Adjustable Output Pressure with DC Solenoid and Integrated High Precision Needle Valve and Bubble Counter : Pet Supplies ## Features - Dual stage construction & adjustable output pressure. Dual stage construction provides stable output pressure regardless of how much CO2 gas remains inside the CO2 cylinder, eliminating unpredictable catastrophes such as an end-of-tank-dump (EoTD). The output pressure is adjustable from 0-65 PSI based on customers’ different needs. - Modular manifold block design. Two manifold blocks are included. Each block comes with its own high-precision needle valve and can be operated independently. You may use one block for one aquarium or use both for two aquariums. - Safety and precision in mind. Our regulator has a built-in safety valve. It will open automatically to release the pressure when it exceeds 100 PSI. The integrated needle valve is precise. The CO2 output can be adjusted to as low as 1 bubble every 3 seconds. - Solenoid runs on 12V DC instead of conventional 120V AC. This regulator adapts to 12V DC, which is more stable and consumes less power. The solenoid is safe to touch and is very quiet. This solenoid is designed to work with an automatic timer. - Attention. Suitable for North American CO2 cylinder with CGA320 adapter! Installation tools are included. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0838KXK5D | | ASIN | B0838KXK5D | | Best Sellers Rank | #44,238 in Pet Supplies ( See Top 100 in Pet Supplies ) #151 in Aquarium Air Pump Accessories | | Brand Name | FZONE | | Customer Reviews | 4.2 4.2 out of 5 stars (645) | | Date First Available | May 22, 2020 | | Is Discontinued By Manufacturer | No | | Item Form | Gas | | Item model number | 2020pro | | Manufacturer | FZONE | | Manufacturer | FZONE | | Model Number | 2020pro | | Pet Type | Fish | | Product Dimensions | 7.56 x 2.56 x 6.69 inches; 2.4 Pounds | | Target Species | Fish | | UPC | 764595878757 | | Unit Count | 1 Count | ## Product Details - **Brand:** FZONE - **Item Form:** Gas - **Manufacturer:** FZONE - **Pet Type:** Fish - **Unit Count:** 1 Count ## Images ![FZ-2020PRO - Image 1](https://m.media-amazon.com/images/I/61yDfO0yweL.jpg) ## Questions & Answers **Q: The needle valve isn't very good. The bubble count drifts often. Is there a way to manage this? Or change out for a better needle valve?** A: I don’t have that problem with either of mine. The needle valve is a secondary regulation device. Try adjusting the primary regulator valve down. This will reduce pressure to the needle valve. **Q: I just set up the regulator. But i see that even with the power off, bubbles are coming out of the bubble counter. Is this normal?** A: No. That is not normal. The solenoid should shut off the flow completely. However, make sure you do not have the regulator pressure set too high. The regulator should be set to the lowest pressure that will allow bubbles to flow. Mine runs a little over 20 psi. If the pressure is set to high, the solenoid might leak. **Q: what size wrench do i need to tighten this regulator onto the bottle of co2?** A: I just use an adjustable monkey wrench on mine. You don’t have to tighten it incredibly tight. **Q: would I need a stand-alone check valve when using this regulator with an inline diffuser?** A: The manufacturer says the bubble counter has an integrated check valve. So no. But I would! ## Frequently Bought Together - FZONE Pro Series Aquarium Dual Stage CO2 Regulator Adjustable Output Pressure with DC Solenoid and Integrated High Precision Needle Valve and Bubble Counter - FZONE Aquatic CO2 Glass Drop Checker PH Momitor for Aquarium Plant Fish Tank Test CO2 Kit - FZONE 16 feet Aquarium Co2 Proof Tubing 3/16'' ID Black Food Grade Air Line Tubing --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kr/products/204325150-fz-2020pro](https://www.desertcart.kr/products/204325150-fz-2020pro) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-06-20*
