Is the Satellite Freshwater Plus bright enough?!
A lot of hobbyists have been asking us whether the Satellite Freshwater LED Plus (SAT+) is bright enough to grow plants or light a tank that is deeper than 24 inches. The measurement Current USA use is Photosynthetic Active Radiation (PAR) which is measured in micromoles. The more micromoles measured, the brighter it is. We measured the highest PAR readings when the SAT+ was set at yellow on the remote. PAR readings resulted in the following:
Depth in Inches PAR Readings in Micromoles
For planted aquariums, low PAR values can result in stunted growth of plants or lack of pigment. If PAR values are too high, algae blooms and takes over the aquarium. So the optimal amount of light for most hobbyists is the minimum required to sustain healthy growth, which is also referred to as the light compensation point. In nature, aquatic plants grow in depths ranging from just under surface of water to 20ft deep. Some plants such as moss and ferns only require 5 micromoles of light to thrive. So our goal is to reach the light compensation point for best growth with lowest maintenance. From our years of combined experience, 30 micromoles is the light compensation point for most aquatic plants. What about tanks that are deeper than 18 inches? Generally speaking, tanks with depths greater than 18 inches will have a larger opening and which like any other wide topped aquarium, will need another light fixture for optimal light spread. From the PAR readings of the SAT+, it is perfectly suited for planted aquarium hobbyists looking for healthy growth and a low maintenance beautiful planted aquarium.
For hobbyists who would like more light, we will have a Satellite Plant fixture built completely for light output coming out in the near future. Please follow our blog and Facebook page for the newest updates!
