Seem to have had an outbreak of this white stuff on my tank during my fishless cycle. I'm wondering is this is algae? It just seems to swish along with the flow of the water. Doesn't move at all apart from that.

Possibly biofilm. Bacteria also do this in tanks, especially during blooms.

Well I'm glad I don't have to add this to the other list of critters in the tank. Doing your first fishless cycle and being met with a mix of hydra and planaria is interesting to say the least!

If this is just algae or biofilm then I imagine it isn't really a problem.

Looks like it might be the start of a black brush algae growth.

It's been there for over a week and hasn't really changed in shape etc

Well, let's hope I'm wrong. I don't know what else it might be. Strange looking stuff!

A positive sign is that it's been there for a while and hasn't grown into anything else.
