Marine Depot on 3reef.com reef forums. At Marine Depot, we love the challenge of caring for marine life and know first-hand the importance of quality aquarium gear. To us, aquarium technology is like fine art. Nobody loves it more than we do! That is why we scour the world to find the equipment, nutrition and supplements that will most benefit aquarium owners and their wet pets. Our approach to product selection is to carry only products we ourselves would use. 99% of orders placed before 2pm PST (M-F) are shipped the same day and most orders over $175 ship free.
