Gsp

[wstem]

There is some stuff growing on my GSP it looks a little like spider webs. Any ideas?

Could be from a vermatid snail. Not harmful but doesn't look very nice.

theres a type of pod that does this too...sorry, can't remember the name...but either way it's just the way they collect food out of the water columb...no worries
