A funny thing happened the other day when Freoboy was here at the shop, I lifted the outer bell on our siphon to show him the affnan style of reducing coupling on top of the inner pipe, only to find that there was none... Seems that we don't have an Affnan siphon at all..
I must keep a closer eye on whats happening here.Attachment:

And we don't have a breather hose either. But we have two of these siphons that have run without a hitch for about 3 months now. Seems the trick to these was breaking the commonly held rules about siphons. We ran the drain pipe of the siphon right down into the fish tank/sump tank so that the end is always submerged below the water surface...

We also have a little hole underneath, you can see it where the black algae spot is..
Standard bell on top, but no ugly fiddly breather hose. It's funny what happens when you fiddle around trying lots of different things, you tend to lose track of exactly where your up to and what arrangement you have. But it seems that this style of siphon might work fairly well.
