Return Pump Suggestions

[Funky_Fish14]

The tank will be a 51g, but I already have two SEIO 1100's to accompany the return, I dont need a powerful return, but I still want some push. Plumbing will be 1" output split into two lines, I would like to use some sort of wavemaker on the return. In the tank, there will be locline for the return outputs.

Any idea where the best place to look at Bluelines is?

Thanks!

Chris
