I have heaps of this is the bio balls in my sump .......has anyone any idea please

 

[jart]

Are they more white in person than in the photos? And are they stationary?

If yes to both - I made a similar enquiry months ago and the consensus seemed to be that they were small sponges of some sort. Beneficial to the system overall.

Others way more knowledgeable than me will be along shortly, and I could very well be wrong, but happy to be corrected and learn.

[Buddy]

Yeah these are good guys. Don't be surprised if you see hundreds of them in the sump!

This might be a slightly better photo - do they look like this?

no they are not furry looking like that

 

[MagicJ]

Have they been taken out of the water for the photo?

 

[Webb]

Interested in knowing too.
I had a nano get over run with those furry looking things when curing some rock, had to start again as they just kept coming back with a vengeance. Still find them clogging filter media so I clear them out all the time.

These sponges seem to like one particular compartment in my sump. :) Not sure why, but must be some preferred combination of light/flow/temp etc. This compartment has my mini GFO reactor in it. Every few weeks I lift up the reactor and its pump, and knock off all the sponges I can easily access into my cryptic zone. Hoping in a year or so to have the whole zone covered in filtering sponges.

yes, and they are only in the sump.I haven't seen any in the tank

 

[MagicJ]

I think they prefer low light areas, which is why you are more likely to find them in the sump or weir rather than the main display tank.

Do you think they are sponges and not a problem?

 

[MagicJ]

Yes, I do still think they are sponges. A photo of them in the water would make a positive ID easier.
