Aquarium Advice Newbie
I know that live rock has denitrification bacteria on it but what other benefits would it have for a fish only tank? If I had an established tank with biological type media in the filter would it not do the same thing? I plan on starting a 75g tank for a porcupine puffer, harlequin wrasse, and a trigger. I would like to add some live rock just for decoration and the added bacteria. The rock is soo expensive is there another alternative for just the decoration aspect.
