Converting a durso to Bean Animal

[mark]

Been running a Herbie trouble free with dual overflows and float valve ATO for about 3 years now without any problems.

One chamber is my primary, other the emergency where I flow a trickle. No microbubbles even at about 1000gph and ATO keeps level in the sump to about 1/8".

To convert from the twin Dursos basically only needed to remove them from the standpipes they were on, add the gate valve and some playing with a sump baffle and drain line length in my fuge.

Just saying Herbie could work.
