My new tank is FO with a small amount of LR and a lot of base rock. Will corlaine grow even if the nitrates are pretty high due to the use of bio balls and messy fish?
 
To my knowledge, unless the nitrates are high enough to fuel undesirable algae growth, they may actually help the coraline. It is an algae and needs a source of nitrogen for food. If they are high enough to fuel hair algae, or the like, then the pest algae will take a foot hold on the rock and prevent the coraline from spreading ;)
 
Good news for me!! I was hoping that I could grow some coraline in there to cover my PVC circulation system :D
