had a crap morning today when i went to go check on my 180 and realized there was a mini flood. my sump bobber isnt registering when the bobber goes up, it worked prety well and now for it to work i have to push it into the right spot for it to turn the pump on, and unfortunately it doesnt do so on its own. i fiddled around with it yesterday, but it didn't work, well it did for a while. i bought the bobber at home depot for $50 and i really dont want to pay that much again. what do you guys use and do you know of a website or store that has a bobber applicable to an aquarium sump for cheap? many thanks
