Review: Buyer beware. This regulator solenoid does not shut off CO2. Soon as the product arrived, I read the instructions and installed the regulator on my 5lb CO2 tank. Right out the box, the solenoid was faulty and does not shut off the CO2. I then waited for over 4 hours to see if the bubbles in the bubble counter would stop. It did not. I then tried uninstalling the regulator and double checking my fittings. That did not solve the problem. I have to manually turn off the bubble counter for the bubbles to stop. I did a leak test. There were no leaks. Since my aquarium is still cycling, I have no livestock except for plants. Should I continue to use this regulator, IT WILL KILL MY LIVESTOCK. The instructions are very basic and provide no problem solving. There are some grammatical errors in the instructions and the instructions provide no pictures for reference. There is an Allen Key provided but no instructions on how or where to use this tool. Obviously, the durability of this product is simply not there. The accuracy, it may be accurate but it is very difficult to determine since the solenoid is faulty right out the box. The fit is perfect. Sadly, there are videos and reviews from others that have the same issue. Since some have this problem while others do not, you purchase this product on a gamble that perhaps yours may work. *****Update******* Change 1 star to 5 star. I was able to find a YouTube video by FZone Studios that shows how to take apart the solenoid to adjust the spring. Once I followed what the video instructed, the solenoid now works perfectly. What the video recommends is to take apart the solenoid, check for dirt/dust, unscrew the 2 screws to release the plate, then check the spring and stretch the spring a little bit. Reinstall the plate and solenoid and test to see if the solenoid shuts off the CO2. Once I did this, the CO2 shuts off within 5-10 minutes as the seller stated. The product works perfectly now. ## Features - UPDATED SPLIT-TYPE DC SOLENOID!

C02 will not come through.** A: Possibly. If you've eliminated the cord and the outlet then it's going to be a problem with the solenoid. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by G***. on 8 December 2025* Bel appareil mais dommage que la notice ne soit qu'en anglais. ### ⭐⭐⭐⭐⭐ Review *by J***N on 23 October 2025* Buyer beware.

No he tenido ningún problema con el kit, que funciona perfectamente, pero posiblemente lo cambie por su versión de dos etapas con dos válvulas de aguja, para que me sirva para dos acuarios. El único inconveniente que le veo a este kit es que no se puede graduar la presión de salida del CO2 y con una presión baja hay difusores que no funcionan. No es el caso de este kit. Dependiendo de lo que uses para diluir el gas en el agua necesitas más o menos presión. Con un reactor de CO2 necesitas poca presión de salida y con un difusor cerámico o de cristal una presión más alta porque el poro que tiene que atravesar es muy pequeño. Yo he utilizado este kit con un difusor y funciona perfectamente. Lo recomiendo. ## Frequently Bought Together - FZONE Aquarium Co2 Regulator DC Solenoid with Bubble Counter and Check Valve Plant Grow DIY CO2 System CGA320 Side Open Cylinder - FZONE Aquatic CO2 Glass Drop Checker PH Momitor for Aquarium Plant Fish Tank Test CO2 Kit - Fzone Neo CO2 Diffuser with Customized Ceramic from South Korea(L-24mm) --- ## 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.com.pa/products/538511121-fz-0100](https://www.desertcart.com.pa/products/538511121-fz-0100) --- *Product available on Desertcart Panama* *Store origin: PA* *Last updated: 2026-05-08*
