seio m820 - Aquarium Advice

02-07-2006, 08:02 PM

I just recieved my SEIO M820 from marineandreef.com.
It comes configured with the 90 degree bend at the bottom.
Everything I read on here says to change the config to the stunze style for more flow.

I hope I'm not missing the part but when I unscrew the 9o off there is nothing to screw back on to it.

Do these come with a screw on without the 90?

I figured out that the 90 just comes off with a little twisting.

Man I'm good.

I have two m820 on timers, so they alternate. These are great power heads.

are these powerheads quiet?

They are very quiet whilst running. Just a little rattle upon startup.

so if its hooked up to a wavemaker it will rattle everytime it switches over?

Only one of my 2 seio rattles, but it occurs occasionally during switch over. Perhaps it needs cleaning. Since I have gotten used to the rattle, it doesn't bottle me anymore. Nevertheless, the wave they make is much better than conventional PH.

I thought you were not supposed to run them on a timer? I have a 620 ant it is great. I remember the instructions not be very good on showing how to configure it like a tunze pump but it can be done.
