The most important part of choosing your Flipper is knowing the thickness of the glass or acrylic on your tank. The easiest way to measure most tanks is just to use a tape measure on the edge of the tank. Our general sizing chart is below
Nano: for glass tanks up to 1/4" (6mm) thickness. Usually 25gal or less
Standard: for glass or acrylic tanks 1/4-1/2" (6-12mm).
Max: for glass or acrylic tanks 1/2"-1" (12-24mm) thickness.
Bowfront tanks - Since the glass is curved, you need to upsize your flipper by about 1/8". So for a bowfront with 1/4" thick glass, you would choose the standard Flipper.
