1.3 L Aquarium CO2 System Generator with Regulator Solenoid Valve for Aquarium Plants (G600SMini)

UPDATE: After buying the Clscea co2 system I came across another “mini” system from Chihiros Aqua which looked high quality so out of curiosity I purchased it to compare. After using both systems for a few days my original 5-star review is validated. The Clscea system blew it out of the water. The Clscea regulator is much easier to dial-in and maintain its setting whereas the Chihiros regulator would constantly change and in some cases completely stop the flow of co2. If you want a budget co2 system it doesn’t get better than the Clscea.I’ve been in the nature aquarium hobby for quite some time and have used CO2 systems that cost quadruple this price. I was very hesitant to try a “DIY” CO2 kit since all of my previous systems were pressurized, but that said, I decided to try this out because my nano tank is only 2g and I didn’t want to spend hundreds of dollars on a CO2 system. When I received the kit I was surprised with the quality the canister and most of the components – the biggest downside is the included diffuser which is made of cheap plastic. While the diffuser does work, I would definitely recommend buying a higher quality diffuser and one sized for your tank.Set-up was really easy however I wish Clscea included a scoop for the ingredients instead of simply instructing you to use “grams”. I took another reviewers advice and used a 1/4 cup however I don’t think that measurement is entirely accurate so I’d recommend using a coffee scale if you have one. Overall everything went smoothly – just remember to install the inner filter first before screwing on the regulator. Now that I’ve had the system running for a few days I will say I’m incredibly impressed with how easy it was to set-up and the quality of the solenoid and regulator. Because my tank is so small I needed a really precise regulator to get to ~5-6 bubbles per second and I had zero issues achieving that with this kit. I also have the solenoid on a timer and it works perfectly without any change to the regulator setting after turning back on.Overall I highly recommend this kit (so far) as long as the solenoid doesn’t require maintenance too often, that’s really the only potential downside. Good news is Clscea does sell parts on Amazon in case you need too replace it. But OOTB for the price I definitely recommend giving this a try.
