Lee's 2-Inch Wooden Air Diffuser, 2-Pack

This shipper (accidentally?) included a cheap plastic bag that the chinese manufacturer must have originally put these in. It is all Chinese except for saying "AquaValue" at the top and there is a diagram of how to use these in an aquarium that is labelled in chinese. The diffuers are now sealed in a nice blister pack in all-english. Why they included the weird all-chinese bag with this is beyond me.

Anyway, they work wonderfully. I'm using them to create small bubbles to diffuse CO2 in a planted tank. They make much finer bubbles than my air stones that I was using previously and my CO2 concentration has improved. I can't comment on how well these would work in a protein skimmer. I always used an injection-powered Aqua-C skimmer so I wouldn't have to mess with replacement parts like this all the time. The main downside to these is that wood floats duh. I hadn't really considered this and these don't come with any suction cups to hold them down, so unless you have suction cups for your air hoses already, you're going to have to buy them or hook the hose under an ornament or rock. I realize that this is the case with all bubblers since they're filled with air, but these are REALLY buoyant.

Theses air diffusers supply abundant micro air bubbles that create the foam inside my protein skimmer. Long lasting, however they need to be kept on continuously, if shut off for awhile then the bubbles will be large but will become micro again after running enough hours.

I used these for many years in my aquariums and thy were the best for diffusing air into water and now I use them in my boat's live well. These are great. They are so much better than the ceramic stones because when bounced around in the bottom of the live well they do not break as the other do. BUT most of all they diffuse so much more oxygen into the water
