With the frag700reef I finally have the confidence in fullLED to get the last 8x T5 tubes out.
Replaced 8x54 watt T5 for 4x54 watt LED strips
There were already 7x54watt LED strips in it, now the total is 11x54watt.
The total power consumption goes from 950 watts to 750 watts
I am not completely satisfied yet, but that will be because the corals still has to adjust to the new lighting. In the near future I will be playing with different color combinations to get the most out of this reef.
