Help with cleaning my air stone

Question

how do you clean a flexiable airstone my one is hardly working

Answer 1

I don't have my curtain set up yet [my first, I just got it today] so I'm not sure how to clean those just quite yet.

For my airstone though, when stuff builds up, I just use an old toothbrush [has only been used for aquarium things like filters and the airstone] and just scrub at it for a while, rinse it and put it back in.

Answer 2

mine looks like a white stick (idk if yours is like mine) but algae and other gunk builds up on it. what i do is rub the big stuff off then take sand paper and rub it down. then i rinse it all off and put it back in the tank. takes 2 mins.... thats if we have the same kind

Answer 3

Do you have an air pump regulator?  Or maybe your air pump is just not strong enough?
