Greetings,

I searched on here for previous posts and found a lot of different and conflicting information about lighting schedules. Some people say never to leave your MH on for longer than 4 hours, others have it on for 10. Some people do a complicated actenic/MH schedule others not.

I have a 75 gallon main tank with 2 65w actenic PC's that I leave on for 8 hours. I have 2 MH 150w bulbs that click on in the middle of that time for 3.5 hours. I have a mix of coral types hards and softs. I am not getting a lot of growth right now than when I had with full PC lighting on a 55 gal tank with a much more aggressive lighting schedule. I also have 2 more 65w white pc bulbs I just don't use since I invested in MH. My fuge light is on at night with 1 65w PC white and turns on dusk to dawn.

I am feeling about stepping up my lighting, but again I've heard so much conflicting advice even on these forums. What kind of setup would you make with what I have? I've thought about doing some exotic setups.. I just feel like the 2 actenics are so far too little light for the majority of the time but I dont want to burn the whole tank blowing MH for a long time.
