What does AIO mean?

AIO or All-In-One refers to an aquarium that contains all filtration chambers in one system. That means the baffles, overflow, and return chambers are all integrated into the aquarium instead of being separated into an external sump like the Marine X, Frag, Reef, Peninsula models.

Update: As of June 2019, the AIO units will no longer come with a return pump but filtration media such as carbon, bio balls and filter socks are still included. If you need help selecting a pump for any of our AIO models please let us know and we would be happy to assist.
