White Sponge Growing Under Zoanthids

BaleKlocoon · 06/11/2018, 03:28 PM

Follow link for picture. It is not a very beautiful sponge in my opinion, but my real concern is that it takes over the zoanthids, blocks their light, and kills them. Should this be a concern? I tried ripping the sponge off with my fingers, but it grew right back. Also I dipped in a 3% hydrogen peroxide solution, not diluted with any water, for about 3 minutes for a completely different issue and that didn't kill the sponge. Would Coral Rx coral dip kill the sponge? Should I just not worry about it and let the sponge do its thing?

I would just it it be, but if it does start to encroach on your zoanthids just rip it off like before.

You should be able to use a soft toothbrush to brush it off.

Throw it in your sump. Extra filter media.

Throw the sponge pieces I rip off in my sump? Won't they just clog up my pump? And won't they die without light?

The value of sponges is debatable; some see them as a beneficial filter, others as an organism that irritates corals competes for nutrients with them. That said they do not need light and many do not do well under bright lighting. Personally I would brush off the sponge and use a fine net to catch as much of the sponge as practical.
