Work SMART not hard!!! and inexpensive... and FAST!!! neither automated or buckets.... Extended siphon hose with more lengths of hose from local home improvement store...
When I'm doing water change or water change with sand cleaning, I mark my water removal level on tank front with magnetized something, then GO... water drains right up the wide siphon, out the tank, out the door, across the back of house, into side yard, over by fence.... No backbreaking water lugging!!! Here are my siphons, regular length hose and L.O.N.G. length hose (but only seeing tiny bit of L.O.N.G. hose) When stored in bin they roll inside 58Q/55L storage bin (23"x16"x12") If getting hoses to extend yours, get thickwall tubing to reduce kinks and keep flow FLOWING
