I use python like device to vaccum the substrate in unplanted tank's as this is where the majority of dirt,crud,poo,etc collect's.
For just water changes,,I bought double disconnect's (Eheim) and enough proper size hose to reach the nearest door (25 ft in my case).
I ,attached disconnect which is same as disconnect's on my filter (Eheim) to one end of extra hose,and after shutting off the filter, closing top diconnect from return hose,attaching the disconnect and extra hose to the return on my filter,, I can then plug filter back in and water that normally return's to the tank,,now snakes across the floor and outdoors to water plant's, or whatever.
Got the idea from Photo of FX5 canister filter which has a drain feature.
I fill the tank back up with the python like device (aqueon water changer).
before this,, I used small submersible pump (100 gal per hour), with pre filter, and section of garden hose to drain water ,and sometimes still do ,,if I'm changing water in two tank's at once.
