What is the optimal PAR readings for a reef tank?
In a reef tank, the optimal PAR (Photosynthetically Active Radiation) levels will depend on the specific species of coral being kept. Some coral species require higher levels of PAR than others, and the optimal PAR levels may also vary depending on the specific growth stage of the coral.
Generally, coral species that are classified as "low light" or "medium light" species will thrive with PAR levels of around 50-200 microwatts per square meter (μmol/m²/sec). These coral species include many soft corals, leather corals, and mushroom corals.
On the other hand, "high light" coral species such as Acropora, Montipora, and other stony corals may require PAR levels of 200-400 μmol/m²/sec or higher to thrive.
It's important to note that PAR levels can vary significantly throughout the tank, so it's important to measure PAR levels at multiple locations in the tank to ensure that all areas are receiving sufficient light. Additionally, it's important to monitor the overall health and growth of the coral to ensure that they are receiving the optimal levels of light for their specific needs.

PAR meter does not qualify for free shipping.
A shipping label for return will be provided which will be deducted from the deposit
All items must be returned in the condition they were received or will result in a loss of deposit. In the event that the par meter is late, the renter will be charged for another billing cycle.
