I've been looking all over for some nozzles to put on the end of air hoses that are connected to an aquarium air pump. It does not need to be adjustable only a little restricting. I've checked wal-mart and all the pet stores but not the fish stores. Im trying to set up a pneumatic rain system, like this: http://www.tincs.com/Pneumatic_Rain.html I know this isn't very practical but I am hoping someone with some aquarium experience can help me out. Thanks in advance.
