Big bros , seniors, pros , do advise please !
Read somewhere that , just blue & white leds are not not enough for corals , especially sps corals , no matter how strong the led lights . Most people say its because corals also require red , green , magenta and other wavelengths of lights . Is that true in your opinions ? If so , where can i find a light with all these colours except for those super expensive lightsets . The cheaper ones like all only blue and white ! Why blue white so cheap but colourful lights so ex .
Thanks in advance .
