THE SEARCH FOR THE FINEST BUBBLER The tale of my quest for the finest bubble-maker:

I confess, I like small bubbles. The finer the better. What I really like is a super-fine mist of microscopic bubbles.
I started out trying to discover the smallestubbler by trying several cheap stone bubblers, they looked like colored sand stuck together in the shape of a cylinder. They all worked the same: big ugly bubbles. Then a I bought what was billed as a premium, fine bubble stone titled "Mist Air" by Kordon. The sand was finer but the bubbles weren't any smaller. Next came a Rena Micro-bubbler tube... still no significant difference. Worse still, it leaked huge bubbles from a poor seal around one end. Then I tried a 2-inch long diffuser that looked like a tube made out of fine white foam plastic. The tube was only about the diameter of a standard plastic air hose. It didn't do any better than any of the earlier products. I tried an un-named wood block diffuser and it showed promise so I stepped up to the premium wooden air diffuser by Lee's. They drill a hole in a piece of lime wood and let the air leak out of the pores in the wood. This diffuser produced bubbles that were much smaller than anything else I'd tried.
But I'm still not satisfied. A source for creating a mist of super-fine bubbles eludes me.
NEW!!! Bubbler warning! I've noticed that the last two Lee's Lime wood bubblers I used developed a layer of fungus growing out of them in as little as four days, and that was in water treated with an anti-fungus medicine. Since fungus is not what any of us want in a fry tank, I've discontinued using them.
