i just got my 2 4's in today and 1 is really loud will it stop in time?

It might not quiet down. I have a few of those and they are whisper quiet. Sounds like the impeller or the impeller shaft may be installed wrong or defective. Also, read the directions that came with the Power Head and make sure it's assembled all the way. Maybe follow the directions to take it apart (unscrewing the end cap), remove the impeller/shaft and put it all back together. If it still doesn't hush up, take it back and exchange it
Good Luck!

does the guard on the front restrict the flow?

Oh, I'm sure it restricts waterflow to some degree, but my #3 and #4 push pretty hard with the guard.

Mine did that for a few minutes. I took it out and realized the impeller shaft was not aligned with the from guard. There is a hole in the front guard you have to make sure its in that hole. You can't run it with out that guard if thats what you are wanting to do.
Speaking of.. I have a week old "4" and I would like to trade for a "2" if anyone is interested...
