Lighting watts per gallon

[Dez]

I use 7 year old Aqua Illumination SOL Blues. I have an SPS dominant tank. 3 x 75Watt units over a 5x2x2 tank. I set them only to peak at 35% intensity and only for about an hour of peak intensity. You don’t nessesarily need the latest and greatest. I have great growth and colours. Use the T5s as supplementary lighting, they look nice and cover what the Leds don’t. Hope this helps.
