As of today, I can honestly say that all of my test sponge is dead.

On a lighter note, I appear to have some sponge growth (of a different species) on a live rock in my refugium. I'll keep an eye...

A sponge will die very quickly with no water flow, if it has adapted to a constant current lifestyle. If you had sponges in your HOB, that can definately do it.

I keep a "spare" quantity of Chaeto in a capped glass jar of aquarium water in a sunny window.

That way, if my chaeto were ever to completely die, I'd have a backup ball.
