CO2Art Pro-Elite Series Dual Stage CO2 Regulator
Pro-Elite sits at the top of the CO2Art range: dual stage regulation, an integrated 12V DC solenoid, a precision needle valve and a bubble counter with check valve, all on CGA320 threads. The machined body and larger gauges are the visible difference from the Pro-SE, and the unit is aimed at aquarists who want one regulator to serve a tank for years without hunting for replacement parts.
Worth the outlay for high tech aquascapes, competition tanks or anyone running expensive livestock where a pressure spike is unacceptable. Overkill on a 10 gallon shrimp tank. Note the physical size: on a 5 lb cylinder tucked inside a cabinet, measure clearance before ordering, and keep the tank upright so only gas reaches the first stage.
Pros
- Top tier build with machined metal body
- Dual stage regulation, no end of tank dump
- Large, easy to read pressure gauges
- Solenoid works with any mechanical timer
- Spare seals and parts sold by the brand
Cons
- One of the more expensive aquarium units
- Bulky in a tight aquarium cabinet
- More capability than a nano tank needs
