Hi all,

Looking for an ID for a pest which is all over my larger tank. Brown stringy algae-like stuff which likes to bind together with grains of loose sand (I have a triggerfish which kicks up quite a bit of it). The picture shows it against a filter overflow but it also likes to bunch up around nozzles and other places my scrubber doesn't easily reach.

Of course my live rock also gets it, to terrible effect - almost like it's carpeted on. I can usually brush/'turkey-baste' it away but it seems intent on coming back in no time.

Is this cyano or a variety?

Here are a couple more photos, this one from my BioCube 14 which has suffered the same fate. The first is taken after the brown stuff is swirled up in the water - looks like whitish stringy snowflake tendrils floating in the water. The second is what has accumulated in the first chamber where the heater is.

Can anyone confirm these are indeed diatoms?

Thanks!
