I'm fairly versed in the way a Bean Animal works after studying them for awhile and building one for my 300 a couple of years ago.
I'm currently wrapping up a new 125 with a Fiji Cube overflow that is Bean Animal ready with (3) drain holes. The drain holes in the Fiji Cube are too close together to allow the typical upside down U-fitting (made from a couple of 90's) on top of the siphon and open channel stand pipes that you see on all the Bean Animal recommendations. I may be able to shoehorn them in there if I cut down the 90's but it will be close.
That got me thinking.........
Why does the siphon channel even need a fitting? For that matter, why would it even need a stand pipe? I mean, it's a full siphon. What does the down-turned fitting do?
Then taking this one step further; why does the open channel need the same down-turned fitting? The purpose of the open channel is to accept just a trickle of water to allow the siphon channel to be balanced with the return pump. What does the fitting do???
I must be missing something here but why can't a Bean Animal have just 1) an empty bulkhead to run the full siphon, 2) a stand pipe cut the level you want to run in the overflow for an open channel, and 3) a stand pipe cut high to act as an emergency drain?
What purpose do all of the fancy fittings, drilled holes, vent tubes, etc. serve?
ALSO: a Bean Animal is just a Herbie with an extra emergency drain. If my memory serves me, all the drawings of Herbie drains show just (2) standpipes. No fancy fittings on top of the standpipes.
