ReefNewb Posted July 21, 2010 Author Share Posted July 21, 2010 Soooo, not knowing this, I had just moved the liverock from bucket to tank, I hear sponges can't be exposed to oxygen? So does this now render it dead? Quote Link to comment Share on other sites More sharing options...
Robb in Austin Posted July 21, 2010 Share Posted July 21, 2010 I've seen conflicting info on whether it kills sponges. Most of the info out there is yes, it will kill them. I wish I could remember where I read that it didn't. Either way, more will pop up I'm sure. Quote Link to comment Share on other sites More sharing options...

Timfish Posted July 21, 2010 Share Posted July 21, 2010 +7 on the sponge. I've been hearing that about sponges forever that they can't be taken out of the water. I think though you'll find that it didn't bother your sponge at all. I've had numerous occasions when redoing a tank or moving a tank when encrusting sponges like yours or that ubiquitus pink sponge I see have been out of water for extended periods of time and not seem worse for the wear. I've also seen Placospongia sp. sponges on new live rock open up very shortly after being placed in water so SOME species of sponges are certainly capable of surviving days exposed to air and I have a ball sponge, Tethya sp. that gets exposed for about 15 minutes whenever I do a waterchange. It does seem reasonable that a lot of the "finger", "tube", "vase" or "tree" , etc., sponges that we get at our LFS may have issues with necrosis caused by air bubbles trapped inside them when picked up out of the water although my personal experiences with Orange Finger, Axinella sp. is the brief amount of time from bag to tank is not going to cause problems.

+dapettit Posted July 22, 2010 Share Posted July 22, 2010 + a bazillon thats sponge. I have a lot of it in my tank. Natural water filter. I wouldn't worry to much about exposing it to air. That stuff is pretty tuff. Quote Link to comment Share on other sites More sharing options...
