Let's talk flow

Not much at all. More like it delays the flow a little bit. When the surge starts the water level in the bubble reducer quickly rises several inches. Once that's done the flow entering the reducer has to equal the flow going out so the water is moving through at the same rate as normal. You just don't see it quite as much without the bubbles.

Nice. What size pump do you use for the 1.5" sized carlson? Also what do you do to let the air out of the carlson? I've seen a couple different designs, some have problems with siphon not starting etc.

I run most of these off of Mag 5s. It just happens that those tend to work well with the 1 1/2" surge. You do need to make sure your supply rate corresponds with the size of the surge pipe which can be done either by selecting a properly sized pump or by manually throttling down an oversized one. They're pretty forgiving so once you've done the initial setup they'll run very reliably.

Within the bucket I tend to use a larger pipe on the fill side (1 1/2") than on the drain side (1"). The trapped air then just gets pushed through to the bubble reducer.

What about a mag 2? Do you think that would start the siphon on that diameter pipe?

A Mag2 has only half the flow of a Mag5 (250GPH vs 500GPH) so I think that would be pushing it using a standard siphon. I'd probably step down to a 1" siphon.
