ok, i am setting up my sump on my 90g. here is the problem, a friend has his set up with live rock and algae as the filter media. the local fish store says that its not the best idea because the algae takes nutrients and the live rock causes me to do water changes on my sump. on the other had my friend is against the bio balls and sings the benefits of the algae and rock. any experiences or suggestions for what to use? thanks.
