FZONE Pro Series

FZONE Pro Series

FZONE
$135.99

Great value for money! It's completely modular, which is great for larger CO2 tanks and multiple aquarium setups. It's fairly easy to set up, but it also very bulky.

From a reputable company. This is a great regulator, but it is pricey and has some reports of initial issues.

Clscea CO2 Regulator

Clscea CO2 Regulator

Clscea
$52.99

Interesting assembly design. Do need of wrenches or other tools. Not sure if you can call this modular or not as you can easily replace the solenoid bubble counter. Clscea is also an unknown brand.

Full Transparency: I have not used this regulator before. I cannot verify the quality of its intricate design.

ZRDR A:JYF-K303

ZRDR A:JYF-K303

ZRDR
$40.00

This is cheap. Too good to be good, cheap. Be aware of that if you decide to purchase this.

ZRDR CO2 Regulator

ZRDR CO2 Regulator

ZRDR
$40.00

Another cheap entry regulator. However, I would choose FZONE over ZRDR

ZRDR Compact CO2 Regulator

ZRDR Compact CO2 Regulator

ZRDR
$33.99

Just get an FZONE one instead of this… That being said, this is very lightweight and compact.

ZRDR FSQ-Double Meter-BT
