It was the BRS study on growing cheato thay got me to open my wallet wide in my new tank build and use the H380. 300 for fuge light? Yup. Considering the cost of all the other stuff its not out of line. My 29g fuge is packed with alge. Grown both cheato and hair down there and keeps it to a minimum in the display. I do have some in the display but thats ok with me since it feeds my critters that like alge. Whats important is that there is like 1000x more alge in the fuge. The light works great, its quiet and the red glow around the doors looks cool at night when the tank is blue. Colors everywhere. I even see it shining up the overflow that is on the left side where my fuge tank is.
