Well, a bit more progress on the tank today. I got my pump from my friend (Sequence Dart) since he took down his big tank today and downsized. This is the result.
I managed to do all of the outputs with all soft 90 degree bends. All the true union valves are done with flex pvc. I was considering doing the whole thing with flex but I didn't have any in 1 1/2" and I got pieces of plumbing here and there from various friends. The reason the intake has three 90's in it is because I got that whole section from my friend with the pump, so that saved me from buying a ball valve and union. Ideally I would have done it all with soft 90's for decreased resistance, but it was what I had.
Here's another shot of the Oceans Motions:
And full tank shot. Sorry for the bad pictures (late night, low light, cell phone camera)
Thanks for following.
