So currently I'm running the stock bio cube pump but it seems a little lacking and from what I've been reading it is. So I went out yesterday and purchased a MJ1200 like almost everyone suggested and boy was I disappointed. I certainly got the better flow I wanted but I also got the louder humming that my wife complains about every so often. This tank is in the bedroom so it needs to be silent or I can kiss it goodbye =( SO my question is what is the quietest pump with the most flow that I can cram into that chamber?? I heard Eheim is good but their 1000 pump only spits out (I believe) 267 gph. Which is not to much better than stock. Any suggestions are appreciated. Thanks
