Review on 🌿 Enhanced DIY CO2 Generator System Kit: Pressure Gauge, Air Flow Valve and CO2 Diffuser for Optimal Water Plant Growth in Aquariums by Michelle Powell

Great product. If you're reading this, you know how much "normal" CO2 systems cost. My plan is to use it while fully growing my carpet plants. Once they get where I want them, I will wean them off CO2 and eventually turn the system off completely. I don't want all the devices to be there. So this was the perfect solution for me. I have it in a 75 gallon tank with a relatively small diffuser. I use an inexpensive powerhead to move CO2 through a tank and it works great! My only advice is to watch one of the many YouTube videos that show you how to use it. The instructions aren't the worst I've seen coming out of China, but they can lead to nasty misunderstandings. Also note that the valve has a "lock nut" that is easy to miss. Looks like it's part of a valve handle. If you turn it, you could potentially put it in a position where the valve doesn't fully close. This happened to a friend of mine and he thought it was a malfunction. But we just played around with the position of the locknut and finally found the right place for it.
