I have a few rubbermaid containers that are cooking lots of live rocks right now. So I use some of the changd water and do some water changes with these rubbermaids.
Otherwise, i feed it to my porcelain throne.

I use some of it to rinse filter medias. (Chemi-Pure; canister foams; fluidized bed pre-filter foam; yada yada).
Then, to the sewer via the bath tub.
