Review: After work for a while it settles - Great product
Review: Flow rate not adjustable - Nearly impossible to adjust flow rate. Valve control knob rotates completely twice, but to go from 0% to 100% is about a 64th of a rotation. Endlessly frustrating.

### ⭐⭐⭐⭐⭐ After work for a while it settles
*by J***L on December 25, 2025*

Great product

### ⭐ Flow rate not adjustable
*by P***Y on May 6, 2025*

Nearly impossible to adjust flow rate. Valve control knob rotates completely twice, but to go from 0% to 100% is about a 64th of a rotation. Endlessly frustrating.

### ⭐⭐⭐ Potentially Dangerous!
*by H***Y on December 24, 2023*

Great idea, works as intended, easy to use, does the job. All sounds perfect…except one day it could’ve ended real bad. Lucky for me I didn’t have any fish in the tank. CO2 levels raised too fast, my drop checker went yellow only couple of hours of being on. Now I probably could’ve done a better job at double checking the needle valve but then again, why? I had it set to about 2 bps since day one. The pressure always read a bit above the green section but it was steady. I had the manual switch, not the solenoid. Everyday I would turn on the switch and walk away because I assume everything would stay the same after initial setup. It was perfectly good and stable for about 3 weeks, then one random morning I happen to be sitting next to my tank and look over at that drop checker. I immediately inspect the bubble counter and it’s like at 10-15 per second. On its own. I look at the pressure gauge and it’s almost near red. Again I was lucky I didn’t have any fish. Also imagine I had it on the automated solenoid and I wasn’t home. It could’ve gone unnoticed and ended bad. I had to give it three stars only for the reason to catch a buyers eye and read this review. I am a first time CO2 user, so someone could maybe try and flip this on me. And that’ll be ok. But this product is designed for the beginner who doesn’t want to invest in a pressurized system. I believe in the brand. I have purchased the 600s mini and the 900 as well. Fairly recent purchases as well so we’ll see how those hold up.!
