I have had a Seio 820 in my 4" 120gal for about 10 weeks now and have not had a problem. I realy like the seio. It moves the water well. imo. In a six foot tank you would want to get the bigger pumps. The 1500 is rather large and bulky looking so you may want to look at the 1100 in stead.
But that said I agree with Walter....... if you have the money buy the Tunze.
Cheers
