If you are using under gravel filter plates with a power head, some power heads have an optional top air intake. This can be noisy and annoying.
fitting a small air stone to a piece of airline cut to fit, and just sticking out above the waterline not only takes out the bubble noise but reduces the air into smaller-'filtered' bubbles. Making for a quieter,filtered life..lol hope this helps.
