ok I think I had a defective unit from the get go. The whirring noise has changed into a constant clacking noise. Soaking the prop unit in vinegar didn't fix it. I'm going to exchange it on the weekend hopefully if one's still in stock.
Now that i've had it for over a month I can say even though it needs an exchange I really like the unit. It's out of sight and produces a LOT of good flow. I run it on reef crest random full time full power.
edit:problem fixed lol. I realized I had it on the wrong glass thickness setting. I set it to 1/4" when I have 3/8" glass. duh! So it still whirrs but the clacking's gone.
