Avast Marine - The Cannonball
The Cannonball is a 3D printed cover for The Plank. It helps to prevent nuisance algae from growing inside the tube due to overhead lighting. It also reduces salt spray from coating Reef Jerky at the end of the barrel.
Installation
Simply rest the Cannonball on the top of the mounting platform. It can be easily removed to check the flow of water inside the tube, or when doing your regular maintenance inside the tube (recommended to be done monthly). In addition, it can be temporarily removed to drop in a cube of frozen food if you would like to give your fish an added treat.
Updates
Version 1.1 has a built-in gap to prevent moisture from building up inside the cover.
