vortech or tunze?

Tunze.

I've heard way to many complaints of the pumps magnets separating from the impeller in the tank. You end up with your impeller on the bottom of the tank, hopefully it does not break anything on the way down, and you could possibly ruin the motor if it crashes to a hard surface such as tile. I've seen a few people that had 2-3 per tank. I wondered why the impellers were on the sand and was told they separated so often that the owners quit using them due to the hassle.

I looked into Vortech for my tank and was told, by Vortech, that I could not use them on my 3/4" thick acrylic tank and that they do not recommend using them on any acrylic tank. The impellers are known to leave scars on the acrylic due to heat from the motor, vibrations between them, and the possibility that any grit could get caught between the panes and the spinning impeller.

I'm a Vortech man, less obtrusive and the flow algorithims are awesome. Their customer service is top notch also, folk's seem to forget that tunze's had a few issues as well when they were introduced. I just like the neater more compact look.

Cheers,
