Tank/Sump Set-Up

[simplycoral]

Hi,

I drain my display tank via dual 1inch overflows down to the sump in my basement. (The two pipes on the left). I then return the water with an external pump; back up to the display (Pipe on the right). If i were to change anything; i would have gone with a more powerful return pump and increased the sizes of the drains & return pipes.

Regards, Simon.
