I make up a 35 gal Brute can of salt h2o in my basement. I have an identical 35 gal brute on wheels near the tank. I start siphoning (mouth siphoning and I use single malt whisky as a mouth disinfectant after siphoning, this adds to the enjoyment of my weekly water change). I siphon out detritus , etc. into the brute on wheels.
After I pull out a full can upstairs, I plug in my pump from my fresh salt water in the basement and pump right into the display tank, usually down behind the rock work. When done, I have a smaller submersible pump I use to pump my old water down the kitchen sink.
No bucket hauling or dumping .
That's how I do it.
