My CFL over my 55 gallon are old and need replaced The hood is a JBJ and houses 2 96 w bulbs ( ~ 32 inches long each). I run one at a time( 2 watts/gallon) since I have a low tech tank ( dosing wiith liquid Carbon source). The plants look OK - growing well and with some brown algae on the leaves and substrate and few clumps of hair or staghorm algae( few mm long on just a few leaves)- not much. My question is which 2 lights would you purchase to replace the 2-6700k daylight bulbs: 2- 96 Watt Blue/White Combo/6500K Compact Fluorescent or 1- 96 Watt 7100K Blue Compact Fluorescent with 1-96 Watt 6500K Daylight Compact Fluorescent or lastly 2-96 Watt 6500K Daylight Compact Fluorescent. Is the 96 w 7100 blue ok for fresh water plants? From what I have read the fresh water plants need both light wavelengths in the red and blue range( not really the green range). The supplier states the 7100 blue is not for fresh water. Although they give me the K rating, the wavelength spectrum isn't given with the description of any bulbs. I believe the K rating between 5000k and 10000K is good for FW plants. CFL of this size are becoming rarer with LED now in vogue so my suppliers are limited. Perhaps I am splitting hairs regarding the 3 choices. Any advice would be great
