Why no purple algae?

[smitas5]

Hi there.. I see all the pictures around the forum and I see a lot of purple algae around aquariums, especially on live rocks.. Where does it come from? I even had some on live rock in my tank, but it's dissapearing now, since it was there from previous owners.. Any ideas? Am. I missing something?

Its called coraline algea grows with when calcium, alk and the paramaters are in check, it takes a while to grow and get re-etablished if you moved or changed tanks

purple up will accelerate the process ...

Urchins will eat it. Stock lots of urchins. Hate that purple crap!

How do you like red or green coraline?
