What is a par meter aquarium?

Ensure proper light levels for underwater photosynthesis.

What is par Reef?

PAR is an acronym for Photosynthetic Available Radiation or Photosynthetic Active Radiation. For the purpose of keeping an aquarium, PAR is the amount / intensity of light that is in the proper spectrum for corals to utilize.

Is Lux the same as PAR?

you are right LUX and PAR are not the same. LUX meters measure the amount of usable light for humans while PAR meters measure a spectral range including how many photons fall on the the plants in 1 sec within that spectral range.

Why are PAR meters so expensive?

All PAR meters are made with a sensor that counts individual photons (“particles” of light). Better filters and sensors typically cost more and so increase the price of the PAR meter. Because no filter material or sensor is perfect, these meters are calibrated to “average” light spectra, such as natural sunlight.

Is LUX the same as PAR?

Do I need a PAR meter?

PAR meters are an important tool for growers and they provide useful data about the total amount of photosynthetic light being transmitted to the sensor. LUX or Light meters on the other hand, which are far cheaper, provide data about the total amount of visible light being transmitted to the sensor.

How much Par is SPS?

200-300 par is considered the ideal range for most sps. Many can take a lot more if acclimated.

How much par is too much Reef?

Too much light will inhibit or harm the corals. There is no absolute rule on the perfect PAR for all corals, but a good starting point is 150 to 250 PAR.

What is Ppfd meter?

PPFD and PAR PPFD, which stands for photosynthetic photon flux density, is a measurement of photons that cover a square meter per second. The photons are represented in the 400-700nm range of the visible light spectrum. Plants rely on a different spectrum of light than we humans do.
