## Questions & Answers

**Q: Hi, do you sell with 21.8 connector instead of CGA320 ?**
A: Sorry we don't have that.

**Q: Does this regulator fit a standard CO2 tank**
A: Yes it does fit a standard Co2 tank.

**Q: Do i have to buy two if im using a splitter for two tanks or does one control both?**
A: The solenoid with bubble counter only can be used for one tank.

**Q: If the solenoid is not making a clicking sound does that mean it’s not working? 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.

### ⭐⭐⭐⭐⭐ Well built regulator for a larger tank and great customer support!!
*by J***. on 11 January 2020*

I've been doing high-tech planted tanks for nearly a decade years now. When I bought this unit, I did a lot of research to find the best balance of price, quality, and size. Now that I have the FZone, I couldn't be happier, it is exactly what I was hoping for. Overall satisfaction with product: High Impression of build quality: High Product feels very solid. There is no plastic on it. I expect it will last for years to come. Impression of Needle Valve: High I’ve used a lot of needle valves over the years, and this one is the best I’ve used. It has fine grain control over the bubble count; and once set it does not seem to drift. I appreciated the inscription showing which direction to turn; as this is a frustrating guessing game on other regulators. Impression of Regulator: High Adjustment of the regulator is straightforward. Once set; it does not seem to gain or lose output pressure. Impression of Bubble Counter: High It looks clean, professional, and exactly like what you want on your showcase tank. Reading the bubbles is straightforward and consistent. Impression of Pressure Gauge: High The gauges are large, written in psi and kg/cm2, and easy to read. Having the second 'tank' pressure gauge helps identify when the tank is getting low, that way I have the chance to refill it before it runs out. Impression of Relay: High I appreciated the quick-disconnect near the relay; as my electrical strip/outlet is not easy to access. Impression of unboxing/accessories: High The packaging is what I would expect from a high-quality product. It includes a bottle wrench; which I was happy to have when I needed it. I was also pleased to see an extra set of o-rings was included; no manufacturer thinks to do this anymore. Impression of Customer Support : Very High I have reached out to Fzone with minor issues in the past. They responded very quickly and were very personable and helped me with my issue. I was very impressed. Just try to get that kind of customer service or product quality commitment from the big guys! Overall, it’s hard to not see that FZone wants to be the best in the industry. If they continue producing products like this and supporting their customers like they did for me in the past; I believe they will achieve it quickly.
