Seio's are nice, but the experience I've had with them, Next time I would just put down the money for the Tunze. But biggest issue I've found with the seios are they don't come back on when they are turned off. So your power goes out, when it comes back on, chances are the seios will not comeback on by them selfs. You have to shake them or turn start the impeller by hand. When they are running they are great. But keeping them running is the problem. You also can't put them on controls that would switch the pumps on and off, like for different movements. or feeding, and at night, Seios you have to use a seio controler, that powers them down from 100% to 50% that way they aren't actually turned off. If you can get seios, then get them.. I've heard alot about doing Maxi jet mods, that increases the power of the maxi-jet to almost as powerful as a tunze. but I've heard mixed reviews on those. But mostly I hear that after you do a mod on the maxi jet, they just don't last too long. But that was about a year ago. and maybe by now they figured some things out. and improved the mod.
