I have a question that I need help with. What is the preferred length of time corals should get light? I have 250w MH and many people tell me different things. Someone told me the more light I give the corals the better it is, as in the ocean they get light at least 12 hours a day. Then, someone else told me to keep the T5?s on for at least 12 hours with the MH for only 2 to 4 hours a day. I am not sure which is right, but I am hoping to get some input as to what is preferable. Many thanks!
