Hi guys,

Been running a small fowlr for over a couple of years now and have recently been fighting something. Any help with ID appreciated.

This appears to be hair algae (the wider filaments) infested with a very thin filament cyanobacteria. I would interpret this to mean that the hair algae is not doing well.
 
Wow, this is your fist post in 2 years.

I don’t use microscopes, so I can’t help there. I trust what Dan says and I can see the Cynobacteria.

I suspect you need some janitors. I like snails. Also depending on what fish you have, consider ornamental macro algae.

If you would, post a full tank shot under white light

I know, time flies right!?

I'll post a tank pic when I get home tonight

Thanks Dan. Sample taken from a small surface skimmer so high up in the tank. Is this also cyano and would you know what the dark blobs are?

The magnified shots clarify a bit more.
It's a strand of gha as @Dan_P said, but with attached strands of diatoms I think.
Sometimes these attach in these funky zig-zag strand shapes

At first I thought this was a string of diatoms, but when I looked closer, it looks like crumpled filamentous algae. The dark blobs could just be clumps of biofilm, possibly bacteria.
 
So, are we saying diatoms or cyano possibly or both?
