Top Down Photo Box
The Top Down Photo Box is an acrylic box designed to take pictures of your reef from above, penetrating the surface of the water to avoid ripples and reflections. The DSLR camera is secured to the box with the tripod mounting screw.
The internal area fits most DSLR cameras nicely.
You can also use this to view your reef from above, holding it by the hanger section to see anywhere you prefer.
