BAOSHISHAN 2L Aquarium Co2 System with Precision Regulator, External Thread Co2 Generator System with Dual Safety Valves & Solenoid, Complete Set for Aquarium Plant

works great has been running for over three months for six hrs a day on timer meter still shows high in green area

It worked perfectly at first, and I had no issues until about a week ago when it suddenly stopped releasing CO2. I emptied and refilled the system to ensure it wasn't just out of gas, and I confirmed there are no leaks. Despite this, it still won't release any CO2.

The tank is quite good and it works nicely (so far, less than a week from the first launch). However, its solenoid valve doesn’t do anything at all: whether or not it is on (the green indicator LED on), the gas is bubbling with the same rate. UPDATE: after I had disassembled the valve (found a pice of advice on a specialized forum), stared at its guts menacingly and then assembled it again, it changed its mind and started to work. I am not sure whether it was a stuck spring or my threatening stare, but… so far so good.

It's a decent DIY solution that's much better than doing it yourself in a 2L bottle. Does it have its challenges? Absolutely. It's not like a typical CO2 regulator that is just filled up with gas that you pump into your diffuser. This uses baking soda and citric acid to generate CO2 and if done properly, is highly effective. But due to its design, you do still need to pay careful attention to your drop checker and the overall consistency of the CO2 output is dependent on a lot of other factors as well like temperature and how long it has left in its monthly cycle.

Súper bien

Received product and worked doesn’t leak but the magnetic Solinoid did not work so I can’t say the product worked right, the paining on the valves was also scratched and I did not like that seeing as this is a new product I am going to let the gas finish and return it was not happy with what I received

I have been wanting to get a CO2 system in my aquarium for a while and was overwhelmed with everything I looked into. This system so far has been easy to set up and I really like that I won’t have to deal with CO2 cartridges. The idea of ‘making’ my own CO2 with easy to find ingredients is quite clever. This system looks a lot nicer than a 2 liter and rubber hoses running into my aquarium. The instructions were clear and the process of putting it together wasn’t simple but I got it figured it, a lot of user error was involved. This system is pricy but when you add up all the parts that you would need to buy in order to get the it running, you’d be saving quite a bit. I have a glass CO2 tester than has been really helpful to show me what level the CO2 is and that has helped me a lot when it comes to making adjustments.

Co2 DIY system, who knew! Just get the ingredients and do so in the instructions, it really does work to produce Co2 for your tank. DO NOT LET THIS THING RUN ON ITS OWN!! It WORKS but it is not SAFE. you will need to keep an eye on it, do not rely on the automated process or timers, the solenoid valve has a MULTI HOUR LONG DELAY. You need to turn it off 4 or so hours before you'd like the injection to stop, it will continue injecting for the entire time even once electricity is completely cut. Either buy another solenoid valve separate or only use this manually! I stopped using it for this purpose.
