Thanks Jason I re looked at the post and all I can say is if anyone is using a siphon to a lower tank rather then a type of controlled gravity overflow then its just a matter of time be for a flood will happen.. All I could suggest is to add a low water float switch cut off to control the pump at the desired level in the top tank and just a bit lower then the pump control switch the siphon pick up of water to the siphon fed lower tank. That way siphon breaks when the pump switch opens and then you limit the mess a bit.
