Anyone know anything about sea sponge?

Did you have them out of the water at any point? Even transfering them out of the bag?

[Discustopia]

actually, even bubbles from your skimmer that stray into the tank or if your sump cavitates and blows bubbles are dangerous

As the bubble rises through the sponge it kills the surfaces it touches - sensitivity varies sponge to sponge. especially deep water spponges are not used to any air bubble contact

no i was informed not to let air touch them. I am going to try to cut off the dead so it does not spead. Hopefully this will stop the spread.
