  I have also noticed this is my planted tank. I did a 50% water change last
Sunday and within minutes had bubbles producing on some leaves. The bubbles
also were only produced on some parts of the leaves. I assumed it was
because I hadn't done a water change for 3 weeks (with exams and all). But I
have noticed it on other occasions.
 I will check it again when I do a water change next weekend.
 Also I live in Sydney, Australia where the water is very clean -or so I
think- compared to other countries.

Glad to know I'm not the only one with this "miracle".
