Hi guys

Sorry if this is not the correct section. I thought perhaps this is the most fitting place to get help.

I have a sponge type of thing(not even sure if its exactly a sponge) taking over my rockwork. Can someone please help me identify this and how I can battle it?

Removing manually doesnt work as it leaves pieces that just grow back.

Thanks

My first question is what kind of issue is the sponge causing that it needs to be removed? How big is your tank? Sponges are a sign of a healthy tank and provide a natural source of water filtration.

Tank is a redsea reefer 170. It has already suffocated a colony of zoa, which I removed, it then continued to spread everywhere in my tank over the rockwork.

I am just surprised I don't see this in other tanks?

I have some that are starting to grow over coral.

Sponges can't tolerate air. If their tubules loose the water in them when exposed to air, it will often not refill and the sponge will die off. Thus if you can bring the rock out of the tank for a few minutes, the Zoas should be fine.

Keep scrubbing them off.

Next question is how old is the tank.
Some get Dustin blooms because if silicates.
You may be getting sponges for the same reason.
Also if your carbon dosing or using Aminos that may also be helping them grow.

Not 100% on this as science is not either, but links stars are rumored to feed on sponges or the bacteria associated with large growths of them.

This would explain my sitiuation. Been dosing vodka for the last couple months and have not ran gfo in a while. I also use a silicate based sand. But my tank has never looked better. The sponges have not caused any issue for me yet.

A fwiw. It's silica. Not silicate.
But other grains in the mix may contain silicates.

Another shot

I was worried about these things but after some research I concluded they aren't bad. This one grew with a host of them under one rock, and have begun to expand up the sides of it. I also have a finger coral on this same rock. Given the filtration factor of sponges I am cautiously hopeful this will leave the finger alone and do its job. It is such a stunning color, I really don't want to get rid of it

Brilliant!! Such a simple tactic for nuisance sponges

BTW. Can anyone tell me what these white curls are? My lfs was vague. They come and go here and there so I don't think they are good but scrubbing them off is not an option. Any thoughts? Answers are better, but I'll take all the info this wonderful group of minds will share

thanks for the info. I new the risk before I used the sand. My tank looks great so I am good. Just thought it was interesting that some one posted a problem.m about sponges just as I noticed them in my tank

Since this is impacting corals air exposure could be a good strategy to remove them. Some angels also like sponges but then you will also carry the risk that corals become a meal as well. If you are using air exposure I would also try to remove as much of the sponge as you can so it does not rot in the tank.

The small white swirls are a form of tube worm like a feather duster. They are just really small. If they grow on the glass you might be able to see the worm with a magnify glass. Normally they are not harmful and their numbers will expand if there is an ample food supply. That is a great looking yellow sponge.

Just an update on a very old thread because I have received a few messages of people experiencing the same issue.
I unfortunately never managed to control this sponge. I ended up shutting the tank that had this down and have since restarted with fresh dead macro in a bid to avoid such pests.

If anyone has any more info on this pest and how to control it please post here as it could help a few people... ;Bookworm
