I'm going one whole year without cleaning my sand. I have sifters that take care of that for me. I do notice some bubbles in the sand that come and go, but from what I read it's the sandbed doing it's job and filtering or cleaning what it's supposed to.
What's the deal with this craze about cleaning your sand bed? I know if it's really deep you may have issues if you do not clean it... but with a 1 inch sand bed, is it really necessary to clean it? Did you have any fish or anything sifting it for you? Doesn't it also help with filtration?
How often would you clean it? How would you clean it? And, if I may ask, what led you to actually clean it?
