Anyone have any idea what's growing in my tank?

Both nitrates and phosphates are both near zero, which I know isn't good.

Cheers,

Looks like dinos. It’s a bacteria.

I'm waiting for a UV to turn up. Just keep removing as much as I can until it turns up.

Installed a UV steriliser on Monday. Scrubbed the rocks to remove what I could. So far so good, the brown stuff seems to not be coming back as fast. I only did one day of lights out, probably should do a couple more.

Agreed. You should do a 3 day blackout if it’s still coming back.

And like you said, try to get your no3 and po4 up.

Does anyone have any idea what this is growing in my sump.

Some kind of sponge/filter feeder. Looks harmless.
