Brown like algae on rocks

[myidz]

Hi, I've got brown like algae growing on the rockwork for about 5 months and it's not going away and I've got a worm like gray growing on the glass. I've attached pictures. I hope this helps and I will attach some parameters.

It's perfectly normal. Don't worry about it.

I agree looks pretty normal. May need to add more clean up crew to get ahead of it.

Looking at your numbers, your nitrates appear to be bottoming out but otherwise I’m not seeing anything overly concerning

As to the worm, looks like it might be eggs or similar. Again nothing huge to worry about from what I can see

Thanks I will add more clean up crew.
