Aquarium Advice Addict
I keep reading air stones are unnatural, and I must disagree to a point. There are plenty of springs, gas pockets and other under water sources that give off bubbles ... Usually not air bubbles though... Methane bubbles ect.
So while having a blue air stone partially buried in the substrate does detract from the natural look, how about covering it with stones in a way so the air bubbles escape through various openings? Yes having a bunch of air bubbles coming from one source doesn't look too natural, but multiple sources can.
I'm wagering that rift valley lakes will have areas where volcanic gases do escape into the water... But I'd have to double check.
