I am making a fat sac pump with a Mayfair 750 gph aerator pump. I have everything put together and it works great, but I am wondering about getting one of those blue water bed nozzles for the end of the hose. I am wondering if anyone can give me a good explanation for why I would need one or what the purpose is to having one. I looked at one at Wal-Mart and noticed that there is no filter or anything that is attached to it. It basically just looks like it spreads the water out as it is pumped out so that the preasure is not all toward one location in the fat sac. I would appreciate any advice anyone has to offer me. Thanks
