Excellent quality and includes freebies!
I purchased this co2 diffuser to go with my Gro co2 regulator. This diffuser has been terrific. What they dont tell you is the diffuser comes with a check valve and syringe should you want to fill the diffuser with water to use as a bubble counter. Ive only had the diffuser for a few months but its been working perfect since day one. Not much to say other than Im happy with this investment. Looks great and puts out a fine fog of co2 mist. My aquascape has been really taking off this last month and I can only guess its my GLA co2 system.
