SRC Member diki88 Posted July 26, 2013 SRC Member Share Posted July 26, 2013 U can google it actually. But it's photosynthetically active radiation. Its another way to measure the amount of lights u need much like how ppl use watts as a measure. PAR is the amount of light ur corals need to photosynthesize and grow much like a plant. The higher the value, the better. However terms like photosaturation and photoinhibition would pop up. Better for u to read it up.

cheemi Posted August 21, 2013 Share Posted August 21, 2013 Shift the zoas higher nearer to light if possible Quote Link to comment Share on other sites More sharing options...
SRC Member dales Posted August 31, 2013 SRC Member Share Posted August 31, 2013 Usually cheap led light not the best option coz they dont produce much or enough light.. Go for high end.. You'll be glad you made the investment.. Quote Link to comment Share on other sites More sharing options...
SRC Member epicfish Posted August 31, 2013 SRC Member Share Posted August 31, 2013 Cheap leds does not meet the required spectrum for maintaining lps. Look for higher end ones like ecoxotic PAR38 or maxspect series for beginners, its affordable and even cheaper second hand. Quote Link to comment Share on other sites More sharing options...
spgohjc Posted September 1, 2013 Share Posted September 1, 2013 Quality lighting is important. Most people believe in the blues as it has better penetration through salt water. But at 2ft, most wavelengths will actually make it through, unless you tell me your tank is more than 100m deep. Two important ranges would be the blue as well as the red spectrum which are important to the zoox. Quote Link to comment Share on other sites More sharing options...
SRC Member solasido Posted September 1, 2013 SRC Member Share Posted September 1, 2013 Zoas or mushroom corals longneck because they are trying to reach for more light. In a simplified term, the led wattage is not enough, also Led needs optics to focus to allow the light to penetrate deeper. The "cheap led" normally does not include the optics.
