Strange white stuff - what is it?

[Andrew Butler]

'Strange white stuff'
Take a look at the photos on the links to my google photos; I have some strange white stuff on my rocks, glass and plants, can anyone tell me what it is? I think it might have taken hold of the Staurogyne repens and turned some a nasty brown which you will see in the 4th photo.

Any help gratefully received

Amano shells? It's hard to say, the quality of the pics doesn't help much...

I had thought some of it is shells from the amano but it doesn't explain it on the glass or it seemingly growing on the Staurogyne Repens. It's a struggle with quality as I'm having to zoom through glass - the photo below is even worse but of the Staurogyne.

Hi all,
I don't know, but it might be the case of an aquatic insect larvae. Have a look at <"Larvae or worm....">.

Chironomid midge larvae also build cases.

and (from <"Bugs you might...">)

Thanks for the input but I'm pretty sure it's not any of the above. I found some tiny snails in the tank today, hacked the staurogyne back hard and found them amongst that so maybe they have contributed somehow.
