Silly question, but here it is anyway: Do I want coralline algae growing in my tank? Why or why not?
I feel like I should know the answer, seeing as I take care of a 75g, but I don't. :help:
If you have it then it shows you have good tank conditions so yes you do want it, plus it makes the rock look better. I think it helps with keeping the nitrates down but not sure where I heard that so i could be wrong.
