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

I installed this in my 75 gallon tank. I recommend this product to get your feet wet when using CO2 without spending a lot of money. You definitely have to play around with it and finding the perfect spirit level can be tricky, but it works well. I haven't had much success with the way the instructions tell you how to start either, for example I don't use this vial. But I squeeze the first bottle into the second to start the reaction.
