FZONE Aquarium CO2 Regulator for CGA320 Side Open CO2 Cylinder
FZONE's CGA320 regulator for side-open CO2 cylinders uses a split-type 12V DC solenoid and a fine-tuning needle valve, with a bubble counter and installation tools included.
Price range: See on Amazon
What we liked
- + Split-type 12V DC solenoid replaces older AC designs, which the listing describes as safer and more stable
- + Needle valve is listed as fine enough to set about 1 bubble every 3 seconds
- + Bubble counter doubles as a check valve against backflow, and the body is hard aluminum alloy with knurled knobs
Trade-offs
- - Fits CGA320 side-open cylinders only, so paintball tanks and disposable cartridges need a different model
- - Listing mentions no dual stage regulation and lists no diffuser or tubing among the included parts
