I'm starting my first saltwater tank and I have never had to plumb a sump before. I have a 120gal tank with two 1" drainage lines and two 3/4" return lines. I purchased a sequence dart pump for the return pump. The issue I'm having is plumbing from the sump to the pump. The sump that I have only has two 1" return bulkhead holes, but the pump has a 2" inlet and a 1.5" outlet. The manual says that the pipe feeding the pump has to be at least 2" so I can't just plumb two 1" lines since that is only 1/2 of the area of a 2" line. Therefore, I was just going to plug up the holes in the sump and run plumbing from the pump over the sump wall and down into the reservoir (see attached image).
I had a go at it yesterday with normal PVC pipe but I think that all of the elbows required to plumb the pump would cause some issues and it looked really awkward. I now think that it would be better to use barbed connections with flexible hose in the same orientation with the checkvalve below the sump water level. I have found a website online with all the parts I need, but decided I would check with you guys before I waste a bunch of money. Is flexible hose logical for this kind of connection? Will I have issues with the pump since I have to run the line over the sump wall? Any suggestions would be greatly appreciated.
