I have a job-101 on a controller and comes on for two minutes and goes off for two minutes. Everytime it turns back on it makes this sort of loud noise almost like a small knock. Does anyone have any advice as to making it more quiet? Should I just leave it continuously? I read and it produces 800gph and it's in a 56 ga tank. Thanks everyone.

No advice except for yes leave it on continuously..
Thats what is going to happen when you put powerheads intended for continuous operation on a wave controller like that..

If you want "waves" (patterns,etc..) then buy a proper powerhead intended for operation like that.. Jebao/Vortech/Tunze,etc..
