I have a pico as well, may i ask how many gal is your pico??
which fixture do you have??
is it the 18"??
What corals do you keep in this pico??
Do you have a picture of your tank?
I have rics, zoas gsp and anthelia and I currently have the 9" coralife 18 watt pc on this tank. I was looking at getting a new fixture the 12" coralife 36 watt pc but then these lights have been recommended by some and other say they are not strong enough for saltwater tanks with corals.
