Review on 🐠 Efficient U.P. Aqua CO2 Inline Atomizer for Aquarium: 3/4-Inch - 16/22mm by Maria Skim

This CO2 diffuser works great and is aesthetically pleasing as it connects to the outlet tube of your filter giving you one less fixture in your aquarium. I bought 5 for my 4 cylinders (1 extra charge for emergency replacement and cleaning). These diffusers are actually more fragile than me. One arrived broken, which RelaxButy kindly replaced. I broke one separating it from the filter tube. Be careful when removing them as they are quite fragile. Please check the product immediately upon receipt, as there is a very high probability that it will be broken! However, high pressure reduces the flow slightly.
