well after a short trip to the local electrical supplier and a small distraction of signing my life away for the next 30 years, the seios are in and running
one is using the casing on it and the other is not. i think i will remove the casing from the second as well
the first thing i noticed was that it was like a little tornado was being turned on
then i noticed that the xenia was almost being blown off the rocks
then i noticed that even though there is about 5x the total flow now, it seems alot more peacefull without the little jets of water from the normal power heads.
all good so far
