hello. This weird red algea has been in my tank, how do I remove it? It’s so ugly and getting everywhere!

Its cyano a bacteria not an algae. Is your tank new?

red slime/cyano bacteria multiple other threads on what to do. search and check them out.

If your tank is new it will just go away on its own most likely..

No, I just did a water test and all parameters are perfect. It’s 8 months old too.

It’s been there for 2 months. I’ll push it out and it grows back. My tank is 8 months old and I did a water test yesterday and it was gold. How do I rid it?

Unfortunately, it looks like mostly dinos to me (in/on the sand). There are tests to confirm, but if your nitrates/phosphates are zilch, it is very likely, especially if you started with all dead rock.

Looks like cyano to me. Bacterial imbalances, nutrient imbalances all play a roll no matter the age of the tank.

not all red slime is cyanobacteria. this thread talks about red slime and how you can possibly id it, then you’ll know how to properly treat.
