The ChaetoMax is a slim LED strip built for growing chaetomorpha and other macroalgae in a sump or all-in-one aquarium refugium. Its 45 LEDs run a narrow spectrum of 420nm blue, 470nm violet, 630nm magenta and 660nm red, leaving out green and yellow light that algae use poorly. At 6.7 by 1.85 by 0.39 inches it tucks behind an AIO chamber or mounts on a sump bracket, so it takes no space in the display. It is a single-purpose light: it grows algae well, but it is not a display light and gives no white viewing output. Owners rate it highly for compact size and algae growth.

Owners rate it very highly and describe it as a compact, effective refugium light that grows chaeto steadily. Praise centers on its slim size, easy mounting and the algae growth it produces.
The ChaetoMax 2-in-1 Refugium LED is a light designed for macro algae growth in refugiums. It uses 45 LEDs with a spectrum tuned for macro algae photosynthesis. The light leaves out green and yellow wavelengths, which targets different parts of a plant's cellular growth structure and avoids wasted energy.
The slim fixture is made for sumps and all-in-one (AIO) aquariums. In an AIO, it attaches with hook and loop and mounts horizontally or vertically, hidden behind the tank. In a sump, it uses a modular bracket mount. It runs on low voltage and does not transfer heat.
