yea idk why people are talking about how ecotech has loud pumps because they arnt. lol unless you have really sensitive ears then yes they are loud. if your really trying to hear for the sounds then yes you will hear them. but with everything running all the sounds drown out the MP's.
It is all very subjective, and ambient noise plays a huge role in what you hear. They are far from loud, but can be annoying on a silent tank. But I would find a tank that is already humming, gurgling, and buzzing annoying already, without the Vortechs.
I've tried them three times, and I never had to try to hear them, they were pretty obvious. But my tank and room is silent. It is just good for others that may need the same silence to know. Both are great pump and great service.
and lastly they are very appealing compared to their competitors. .
Very appealing to you. Not really to me. The smaller footprint in the tank is great for some, to me having a pump on the viewing panes is blah. I have no problem with heat. Tunzes add very little heat.....the entire setup including transformer on the 6105 draws 25 watts, and a fair amount of that is lost to heat in the transformer.
Those of you that claim the vortecs make must either not have them installed properly or have supersonic hearing.
Supersonic hearing is a curse

. I can hear the whine of a lot of some wall transformers, but I can sleep like a ababy with a window air conditioner blasting 2 feet from my head.
The noise has nothing at all to do with alignment, having them misaligned makes a horrible sound. The motor just makes noise, some motors more than others. There is nothing blocking the sound, it is the nature of exposed motors....the Tunzes have the advantage of having water help quiet them....at the cost of more footprint. You could hold just the motor in your hand and hear the same noise I refer to. Not loud by any means, I have had desktop computers that were louder, until I replaced the fan
