I have a 125 gallon 60L X 18W X 26T my tank has been going for about 6 years. I have a Odyssea 322w 60" fixture. I bought on Ebay It has a total of 4 main bulbs 2 1200k daylight one is 96w the other is 65w and 2 true actinic bulbs one is 96w and the other 65w there are also 10 moon led's. I wanted to add two 250w MH bulbs to the tank maybe 15k or 20k but don't know allot about lighting. Or should I add another lighting fixture as above? Any intelligent input would be very helpful. My tank has 6 fish and a hand full of soft corals, and will be adding more soft corals after I get my lighting up to par Thanks Wes
