I just purchased a Hydor Seltz D 1600 for my 55g setup.. how is it working for you?

Wanting to create a manifold to connect it also to my bio reactor!

Just keep in mind, do not restrict the flow coming out of the pump. You want to come out of the pump with max diameter pipe and gradually reduce, as well as avoiding and sharp turns in piping. This keeps from building up back pressure in pump.

Is this a good design?

Would be better if you replaced the 90's with 45's. How big is the pipe coming out of pump?

3/4" Barb - Output of Pump to Manifold (would need a tube only a foot long to reach the pump in the sump)

Cuts to 1/2" with a ball valve to 1/2" quick connect.

Top goes from 3/4" pipe to 1/2" barb for return pipes
(using a foot of tubing to connect to the return going up another 2-3 ft)

You want to come out of the pump at max. size, which I believe is 1.25 inches and gradually decrease from that. Standard PVC fittings will fit onto thread of pump.
