Achieve Accurate Light Settings with the PARwise Aquarium Light Meter

Smart Submersible Quantum (PAR) Sensor

PARwise is ITC Reefculture’s latest tool which ends the question of what setting the aquarium lights should be on, whether that be brightness, color (spectrum), or photoperiod. PARwise empowers reef keepers to make the right decisions over their lighting settings. Perfect growth rates need three things: The correct wavelengths, the correct light intensity, and both for the right amount of time. Light changes with depth and clarity, too, do the requirements of plants and animals. Unfortunately, the human eye is not particularly good at understanding light levels and colors!PARwise provides a simple-to-use light meter that will give you a deep understanding of your lighting and how to tune it to perfection—designed and manufactured in the United Kingdom.
