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

Heres my advice, dont use a 750. Too slow and a waste of time. I have a 2000 gph pump and everyone that has ever used that comments on how fast it fills and drains. Also having the blue nozzle allows you to attach it properly without having to worry about it coming out while moving. The blue nozzle allows you to "thread" it on the fat sac opening for a more secure fit.

Blue nozzles, try these guys- <BR> <BR><a href="http://www.gethighsports.net/Contact.htm" target="_blank">http://www.gethighsports.net/Contact.htm</a>

Duh. Should have read the post first<img src="http://www.wakeworld.com/MB/Discus/clipart/blush.gif" border=0> <BR> <BR>It's just there to keep the sack from sucking shut when you drain. <BR> <BR>On my ballast system, I used to use a piece of 1" OD clear vinyl tubing about 1 foot long, and jam it on a barb fitting that screws on the pump. When you stick it in the sack the 1" tubing is stretched enough around the barb that it seals great at the sack inlet. To remove it, just twist.
