Tunze vs. Seio

[swabearf16]

Request opinions and experiences with these high-output powerheads (500-1000+ gph) . These two brands seemed to be favored for price and performance. Thanks for your time!
P.S. I have a heck of a time with the search engine. For example, if I type in "powerhead", I might end up with results ranging from haircuts to shoelaces. Is there a trick to it?

SEIO Super Flow powerheads doesn't give out very much heat (a plus) and they have low wattage output.

i dont have direct experience with either, but Tunze are good because of two advantages, they are mounted on the outside of your tank and magnetically drive the propeller inside, hence almost no heat transfer whatsoever. and second, the design of the head allows for flow in a radiating pattern and not linear, so more surface area gets affected.

I upgraded 2x SEIO 620 to 2x Tunze 6000. The Tunze units put out a lot more flow even at the lowest setting. I thought my SEIOs were HUGE comparing to my Maxijets. The Tunze units are HUGE, double the size of the SEIO 620.

try typing in aquarium powerheads when doing your search

there is also a new powerhead coming out by hydor called the koralia...designed like the tunze but half the price and magnetic mounts....there is a thread about them here...just type it in the search box

I just got 2 nanostreams by tunze. They are great super quiet and massive flows.
I wanted to wait for the koralias but I couldn't, they are not out yet and the nanostreams are out in limited quanities.
As far as the seios, I believe them to be of low quality. I have read of many people not being able to start there's back up after you turn them off. Until you manually flip the propeller.
tunze very high quality and the nano streams have really nice mounts and can be pointed in any direction. check them out for sure.

Thanks all. Pretty much what I've been hearing. Thanks for the reinforcement.
