Beauty, but version 2 is no longer a cone!
I've been making my own wooden air diffusers for a while now, fiddly work but when I get it right, they're bomber, producing bubbles on all 4 sides. Store bought wooden diffusers that are drilled down the center only bubble on two sides. Have looked at ceramic air stones as well. The Boss Hog brand stones are a bit large but they're about the only non-wooden ones that produce sufficiently small bubbles to be effective in a skimmer. Interested in your attempt at making ceramic stone for version 1. What type of material did you use? Seems like that didn't work too well? Tell me more!
A few photos of my DIY hollow basswood diffusers.
First chunk of basswood I had was a narrow plank, so I first had to glue sections together to make large enough sides
Thickness of panels is important. Too thick & you need a monster air pump.
They last a very long time, I think I ran this one for almost a year.
