Review on 🐠 Discover the Clscea Aquarium DIY CO2 Generator System Kit for a Thriving Underwater Ecosystem! by Barbara Murphy

The kit works great, the only downside is the valve that comes with the system, if you let the pressure go above 1.5 adjusting the bubble rate becomes one real problem. I have returned home 2 times with dangerously high CO2 levels because of the valve, even though I should not have left the CO2 generation system while I was away, so this could be attributed to user error. Great bang for your buck and my plants are thriving on this kit.
