i have a very busy urchin and lots coraline growing having to scrape it off the glass!Lack of Urchins should be an option. I never really had great coralline in my tank at work, but when the urchin i had in there died, it really took off. Granted that also coincided with when I decided to start paying better attention to the tank, but I am sure it was a factor...
Also i believe mine has took off after dosing kh blend 2 or 3 times a week before that nothing.
