75G RR Tank and 1900GPH Pump Setup Help

[sulty]

As the subject says I am setting up a 75G RR tank (offcenter overflow) and I have a Pan World NH-250PS (roughly 1900 GPH).

Now I already have a feeling this pump I got is going to pull water much faster than the tank is going to have coming out, even when I put a stockman pipe on it.

I don't want to use powerheads, and would like to keep plumbing as easy as possible and to a minimum. The refugium I have is a CPR Aqua-fuge pro


With this in mind does anyone have some good tips or ideas on the best way to plumb my pipes to get a great GPH rate from the pump that won't over do the tank, keep it so I won't need power heads, and keep plumbing easy and to a minimum.

I had one thought of using both holes in the tank as drain lines, one to the refugium and the second to feed into the line that runs from the refugium to the pump. I was hoping to get away from and over the back return line, but I am unsure.

Thoughts and suggestions?

In my opinion you should use that pump for a closed loop system and get yourself a smaller pump for the sump/fuge. Maybe something that will give you around 6 or 700 gph after head-loss for the return pump.
The predrilled holes in the tank would be used for the sump/fuge and return line and the Closed loop could go over the back or you could drill the back of the tank to accommodate the closed loop plumbing.

Yeah that pump is going to be wayyyy too big for a 75g, you will have to have a gate valve to control the flow, and I would suggest PVC plumbing it in if you haven't considered that already, with a pump that size, plus throttling it back with a gate valve you run a serious risk of blowing off vynil tubing, even with a hose clamp.

I went for a 950gph pump on my 75gal return, and I ran a T fitting with a tball valve to my CPR refugium. Here is a link to my thread, I'll have updated pictures of how the PVC return project turned out soon, but I have some of the construction photos up on the last page of my thread for now.
