red slime algae

[Rodders]

I have a 10 year mature stable tank.
All parameters are within good boundaries.
I have red slime algae on some rocks.
Possibly where flow is less but still have good flow in tank.
Certainly not too many fish in tank.
Quick fix please?

What do you have for a CUC? Siphon it out larger water change, what are you using for a water source?

We're going to need way more information than what you've provided.

How long has the tank been set up? What is your livestock? What exactly are you parameters? How often are you feeding? How often are you doing water changes and how much? What exactly do you have for flow?
