Glow & Measure with Precision

Bring style and precision to your reef tank with the N-Neon Fluorescent Coral Caliper — a 3D-printed measuring tool crafted from reef-safe PETG fluorescent material. Perfect for measuring coral growth or fish length, this tool glows brilliantly under blue/actinic lighting, turning routine measurements into a visually satisfying ritual.

Pair it with your N-Neon Feeder or N-Clear system for a complete aesthetic and functional reefing setup.

Each N-Neon Feeder is 3D printed and may exhibit minor surface variations, which are normal characteristics of the printing process and do not affect performance.
