Review on 🔧 UA-G515 Tri-CO2 Regulator by UP Aqua by Michelle Marsden

I bought this to replace the regulator that comes with their DIY CO2 setup (about $20 per setup). The old valve quickly stopped maintaining a constant flow. I used it in a 10 gallon aquarium and gassed the fish. This new brass valve is a little better, but not by much. If you're stuck with this low-tech solution, then this valve is for you. The only thing this setup really did was show me why CO2 is good and why people spend a lot of money on a regular CO2 valve. I will continue to use this valve as the best solution for the price.
