What the heck?!?

So I posted this elsewhere thinking it was fish waste but I don't think it is. Some say it's calcium some say fish poop so I was hoping someone could help identify these clumps


Sorry for the bad quality it's a pic from my phone

 

Here's a better clump

 

I'd say sand clumping from bacteria and calcium.

 

Is that bad? I dont dose with calcium or anything. How do i get rid of them?

 

Most likely nothing to worry about. Substrates usually develop a film of beneficial bacteria I wouldn't worry about it at all. If anything, I would say it is a good thing. It means your tank is maturing.

 

Agreed

 

My finely CC substrate sometimes even clumps in small strings, but there is no worm inside.

I think this has been good advice listed.

 

Awesome, i was starting to worry abt it
