A bucket never goes near my tank. I heat two 90L plastic tubs with 2 X 300W aquarium heaters overnight, outside. I have a 20 metre length of plastic tubing I got from Bunnings. I modified a small internal filter pump which has 4 suction cups that attach to the inside of the aquarium and that is connected to one side of the tubing. That gets the syphon going (try sucking on 20 metres of tubing!). The water is drained onto the garden. When the tank has dropped sufficiently the garden end of the tubing is placed on the pond pump in one of the tubs and the flow is reversed. Easy, doesn't take long and no mess!
