overhal Posted February 7, 2011 Share Posted February 7, 2011 Are 4x14 cree xp-e, 1:1 blue/white ratio enough for a 55"x20" x22" high tank? I want to put every coral that comes through my mind. Thank you. Link to comment
evilc66 Posted February 7, 2011 Share Posted February 7, 2011 Not really. The 4 rows is fine, but 14 LEDs will not cover the length of the tank very well. 20 per row would be a lot better. Link to comment

I want to put every coral that comes through my mind. Thank you. General rule of thumb I use is 10-15 square inches of surface space per LED. Taking that into consideration you should be looking at 73-110 LEDs for 1100 sq inches of surface space. To keep SPS on the sand you want to be closer to 10. As evil suggested, 4 rows of 20 leds would put get you 80 LEDs which would put you in the above range and let you keep most corals. Link to comment
