Valous;3978998; said:nice set up on the LED. I just stumbled upon this thread and I think I am going to try to go with this for my new tank that I am working on. I just not sure how many LED I will need for a 220 gal tank, 6'x2'x30. Do you have any idea how many I should be putting on a tank that big? I am going to be using a few blues for night lighting so i can see my catfish swim around.
Just get an output of say 7000 lumens and it will be bright as!!
I've worked on 1000 lumens per foot of tank length at 2.5 wide with good results.
