smaller bore pipe = slower syphone rate.

sorry there, got my lines twisted on my last reply. so i apologise

this would, of course, slow down the rate that water was taken out of the tank.

but it would make it harder to keep the syphon clear of substrate.
because of the the faster speed the water would move at.
