    Purchase this back in Sep 2019 for my low light 29g set up. Works as intended. I has some trial and error with my choice of diffuser. I did not had much luck with glass diffuser since it requires a higher pressure to build up and zero CO2 leaks. My pressure needle barely reaches green. One time the diffuser pop from the line and I gas a couple of Corys. I learned then to keep the magnet suction line about 1/4” below the liquid. To prevent accidents like these. I lower the suction every other day. I have to note I use a solenoid valve and a timer to turn on/off the CO2. This extends the life of the reaction. I also double the dose since I bought big dollar store bottles. This gives me more than a month of CO2. No problem with explosions lol. I recommend the lime wood air diffuser, it works great and diffuses the CO2 perfectly. See in picture behind Betta. Watch out with the orings. If these are not seated well you will lose all your CO2 overnight. Also even if you run out of citric acid you will still get a few more days of CO2 generation. My set up is fluval-88 bubble counter, lime wood air diffuser, SL-1-12V solenoid with 15490-5 manifold from diyco2regulators, and timer. With this set up the cost is near what you would spent on a paintball regulator I think. Overall, I am happy with it. My plants are looking great. In the future I will probably make the jump to regulators to provide a more constant CO2 pressure since I find with this set up I am constantly adjusting the needle valve to get 1-2 bubbles a second.

    I bought three different CO2 diy generators, which is by far the best. These components are more durable than other, less expensive models. The most important thing is that the larger knob on the valve is easy to adjust to get the right amount of air bubbles for your tank. Help yourself a little and spend a few dollars to buy this configuration. Moreover, the description in this case is in English.

    I followed the setup directions and now have CO2 in my planted tank/shrimp breeder tank. So far I’m impressed with how this works.

    Better then I could have hoped. looks professional as well. so that's nice. WORD OF CAUTION: don't over loosen the air valve. the entire needle will come out spewing everything into the B bottle and Causing A LOT of Mess IE: uncontrolled reaction.

    Im new to the hobby, but this works great. BUT! Do not turn the flow up to high. When you start the reaction you'll see about .5kg on the gauge. This is prefectly normal. It wont be in the green but close. If you do open it to much for to makes the reaction happen faster. This causes too much pressure that vents and wastes co2 and your reactive materials. It has a blow off valve that releases co2 when the pressure gets too high. This isn't a bad thing. Keeps anything from exploding. Im not new to high pressure air and this thing is childs play in the grand scheme so dont fear. Completely safe. I run a small 10gal tank long. You want about 1 bubble per 2-3 seconds. If you want to get crazy...1 bubble per 1.5 seconds, but it depends on how big your tank is. This thing could run a larger tank for a week or so. The first two times I used it, it only lasted a week...but that's because I cranked it and played with it a lot. The price is right on this compared to a bottled setup. If you dont mind spending an extra 15 minutes every few weeks(you shouldn't mind if you're into aquariums) then get this.

    It works fine. I just trying to adjust it because the mix don't last the month as expected, but it's just a matter of adjusting and elevating the valve with the magnet to avoid waste the mix if the pressure is under the "green" range.
