LEDs on 6gal Nano

At least!! Worth it though IMO. I had them on the tank for about 2-3 wks at 1/2 power while we waited for the correct power supplies to arrive. Everything in the tank started growing for the 1st time since I've had the tank up. They were off for almost a month (long story) but anyway, I'm excited to see what will happen over the next several months! Before the LEDs my corals only sustained themselves, but didn't really grow or multiply.

 

Awesome.....
