How come so many vortechs for sale?

[Seriak]

I don't really hear mine. I have it at about 70%. Not in pulse though.

I've never had a Tunze so I can't really compare but I think Vortechs are awesome and well worth the money. I could certainly never imagine going back to Koralia. They're like putting footballs in your display tank!
Like some of the others here though - I think I just got used to the noise. That, or maybe its because my living room (where my tank is) is so rarely anywhere near silent anyhow.

I've noticed these new tunzes of mine and near silent however when they get over about 65% the noise increases significantly. Are the vortechs always audible or are they silent when moving less volume?

I guess everything is relative but I find Vortechs to be pretty silent when running any lower than 50%

I don't like the fact that Vortechs are not aimable. I hate having the 'footballs' in my tank too but I didn't want straight water flow in my tank
At least the Koralias are silent

I thought the same way when they first came out but the flow is so significantly different from tunze that I don't miss the aim ability. In fact when I put my tunze back in the tank I hated the strong force of water directly in front of the powerhead and the deadspots in the rest of the tank

True they are not aimable but the stream is wide spread and not a jet stream in one spot. I also find they draw a lot of water up the glass causing a nice movement behind the rocks. I also fund them silent under 60%.

*what Marie said lol*

Just a thought, if you want the Tunze to have a similar wide wave spread like the Vortech, you can modify the output nozzle and the wave will be much wider. I saw off the output nozzle back almost completely, leaving just an 1/8" and the wave is much wider and more gentle. Love it.

You can also modify it like this, it will give you stronger flow too.
