Review on CO2 Art Inline Diffuser Locks by Michelle Eilenstein

As my tests showed these inline diffuser locks are a great way to add carbon dioxide to your aquarium's water filtration system.The diffuser locks help keep your CO2 levels consistent and can be easily adjusted for flow. The lock function ensures that the diffuser stays in place and doesn`t slip out of the tubing. The only con I found was that I wish they were sold in packs of more than one. Overall, highly recommend for any aquarium owner looking to improve their filtration system!
