I saw a post on here a while back detailing the number and type of lights needed for the depth of your tank. Now I cannot find it. Can anyone help?
I am starting up a new tank ( 40 breeder).
It is 36" long, 18 wide and 16 tall. I would like to keep mushrooms, zoas, polyps and maybe some LPS later. So how many t5 bulbs do I need?
Thank you all for your time.
