I have two 18w gyres, two nero3, two return nozzles (using vectra at 60%) and one jebao. Add more flow?What tenius need is a good flow. Light is not as important as you might think.You have enough light already. Metal halides are great if you use a chiller( produce ample heat)
Turn up your intensity on your radions by 10% until you achieve whatever par you want.
Also mwtal halide don't really push a lot of par. I have used them in the past and thier strength is in the coverage of light not so much the high par. 300 to 400 par is what I used to get out of them.
Flow and chemistry come first
