The Carlson device is an autosiphon and I built one and it does not let you have any rep rate you want, there is only one. If you pump water in to slow it won't start and if you pump in to fast it won't stop. I built the toilet valve design and it works great and you can pump at any rate you want so that you can get the rep rate you want.
and look for the surge design page. I built mine in a 20 gallon tub not a 5 gallon bucket but it will work in almost any container.
