Woops sorry NG, I thought you were going after the recirc. model (RC 250) rather than the RS 250. In which case, ignore my comment about Teeing the drain line to feed the skimmer. You simply won't have to now, just put it in your sump in the area of your drain and leave it to work. Definitely mesh mod it though.
As for the Nitrate monitors, I think I remember reading that its designed for freshwater and it won't be as accurate as you need. Same with the Ca. I can't find the article though. Personally, just stick with a regular test kit.
When it comes to plumbing, just use spa flex like Melev suggested. Having less sharp of bends will help keep your flow up from the return pump, and its much better than the clear plastic stuff that you seem to want to stay away from.
If the Oceanic has the option of 3/4" or 1" drains, go for the 1". Two of those should be more than enough to outflow your pump. And bigger than a Mag 12 and you'll want to adapt the 1" into 1.5" or bigger as soon as it comes out of the bulkhead.
Whats with the 3AM posts by the way? Don't you sleep?
