Fireline Optix is a Florida company specializing in sunglasses but with a few very interesting products for the reef aquarium hobby. The Coral Vision C-137 is Fireline Optix’s take on the reef tank viewer which is dual purpose, with both a magnifying lens and an optional add-on fluorescent filter.
These hand built coral viewers are made from a 3D printed frame with strong neodymium magnets for each of the three parts of the C-137. There is a wet side which is a simple magnetic frame, a dry magnifying lens which goes on the outside of the tank walls, and a thin yellow fluorescent filter which can be used optionally in conjunction with the magnifier.
Fireline Optix makes a 60mm ‘Micro’ version which starts at $51 and a regular version which is 90mm in diameter – about the same size as the Portal or DeepSee viewers – for $85. Since the C-137 is made from a 3D printed frame the viewer can be specially ordered in any a wide range of colors, and a customized lettering can also be selected for both sizes of the Coral Vision viewer at additional cost.
