White fluffy things in overflow

[sim2142]

Hi,

Looked into the overflow area of my tank recently and came across these weird white things (I don’t mean the hydroid jellies). The pictures aren’t that good but they all seem to be attached by a single stalk to various areas of the overflow, they don’t move except for swinging in the current. Are they also hydroid jellies?

couldn’t get my camera to focus on any but there are also variations which hang from tendrils around 5mm long, they are only in the dark areas of the overflow.

Any help would be appreciated
