Check Valve?

Haha! That'd be awesome... better than my pen on notebook paper sketch. However, I dont know how much its really necessary...

I appreciate it!

Basically I was just looking to see how it would all fit together. I have:

-a 135 gallon sump that is 72"x24"x16"
-I'll be connecting that to a Reeflo Marlin pump. Between the sump and the pump I'll have a true union ball valve. So there will be some 1.5" between the two... not sure how much.
- leaving the pump I'll have to install an adapter as the pump has a 3/4" outlet, but I'll be setting it up to 1.5" PVC followed by another true union ball valve, then a true union check valve, followed by yet another true union ball valve.

Now this is where I'm trying to figure out how to setup the rest. I'll have to setup the MRC-CR2 and the associate CO2 tank. I figured in the interest of keeping everything closer to the wall, these would be next to the pump (CR2 then tank).

I was thinking about building a table that is 12'x3'. I'd put the sump along the back of the table so that there is a 1' ledge in front of it to work with. Standing in front of the table it would flow with the drain flowing into the sump, through some bubble traps/baffles, into the skimmer chamber with the SRO XP3000, then to the fuge chamber that is going to be lit by a coralife 24" T5 unit, and then into the return section. Then you'd have the pump, then the reactor and tank.

Make sense?

No one needs to build it because i think that'd take someone forever, but if anyone has some changes they think I should make to the setup I'm all ears.

I looked in the basement ceiling this evening and I'll admit... I'm scared about what I'm up against (installing two floor joists while not damaging the drop acoustical tile setup, running the pipes through the floor from above, running the plumbing to the rear of the house with other pipes and wood members in the way).
 
Can i ask why you are using such a big return line.
I don't have a system as big as yours and i'm no hydrodynamacist:confused2:, but it seems to me that you are doubling the amount of water weight that your pump has to overcome. If the overflow capacity is limited to the smallest diameter fitting size the same must be true for returns. Your pump has a 3/4in outlet and if your head is 15ft and my math is correct, that is roughly 5.5lbs of water. For 1.5in pipe (((pi x .75^2) x 180) / 231) x 8 = 11lbs of water.
I may be way off base here... just curious.

Smaller diameter pipe will actually increase head pressure.
 
It is the velocity of the water falling back when power is interrupted that puts undo strain when the pump restarts.
 
I'm using 1.5" because Reeflo recommends that you use 1.5" PVC as much as possible for the return. And for the record... I have NO idea what I'm doing either... just trying to glean as much as I can from people that do :)
