The R80 features a center overflow with 360 degrees of water circulation. The tank itself was designed to accommodate coral frags by using the included Frag Trays. It serves as an excellent way to display and store numerous coral frags without distraction.

The R80 also features a unique glass sump with an integrated ATO reservoir as well as designated dosing container shelves within the electrical box. The R80 and R80CS include an integrated electrical cabinet and pull-out storage drawer located on the right side of the stand.
