I use a platform, like they use for DIY. On there I put two beer buckets, one marked OUT, one marked IN. Only fresh water is put in the IN bucket to prevent transfer of anything between tanks. The OUT is used to place the initial water from the tank to then enable cleaning of the external filters etc.
I have one hose for OUT and one for IN. The OUT gets started off with a pump attached to my drill, then it will automatically continue on its own. This way I can ensure nothing is transferred between tanks, as I bleach the syphon what I attach to the hose. The hose goes straight down the bath or onto the garden, but NOT the veggie patch!
For IN, the hose is attached to bath taps with a Y set up, and then drawn into the IN bucket, monitoring the temperature. I have got this down to a knack now, so then the WHALE STYLE PUMP, pumps the fresh water, which is mixed with Seachem Prime into the aquarium.
Easy peasy, no back ache
