Have had three Rena sponges sitting in the sump for over a year. Lots of life in them (coralline on at least one, small pods, maybe even some feather dusters). Just hate to see anything go to waste. Would be great to cycle in a new tank. Will hold onto these for two days then I am afraid I have to trash them, they've served their purpose for me. Located in Red Deer.
EDIT: looks like these are spoken for by a local
