Accurate lighting is key to coral health and growth, and PAR meters help you dial in the right intensity for your reef tank. Whether you're setting up a new system or fine-tuning an established one, measuring PAR (Photosynthetically Active Radiation) gives you insight into how much usable light your corals are actually receiving. This collection includes trusted PAR meter models designed specifically for aquarium use—so you can make informed lighting decisions.
From handheld options to Bluetooth-enabled sensors, these tools are ideal for reefers who want consistent results and healthier corals. A reliable PAR meter for saltwater aquariums takes the guesswork out of lighting placement and helps ensure your tank gets the coverage it needs. Whether you're running LEDs, T5s, or metal halides, having a PAR meter on hand can make a measurable difference in your reef's success.
