Red algae

[typezero]

I agree with above. Red slime does come here and there for me but in the start it was bad. I only found a multi pronged approached worked for me.
Increase internal flow
Decrease nutrients (feeding)
More water changes
Decrease lighting temporarily
With manual stiring and turkey basting of sand and rock
And i also dosed micro bactor7 with kz coralsnow

It cleared up for me in about 2 weeks. I get it now and then but just small patches and its gone next day when i tweek my biopellets.
