I just purchased a 180 gallon 6'x2'x2 to upgrade from my 90 gallon. I'm currently using a 6 bulb 48" t5 retro with 2 reef rite led strips. I was thinking on using these same lights and adding 2 more t5s then staggering the bulbs to get coverage. Do you guys think this will give enough light or should I switch out my ballasts and reflectors so I could go with the full length bulbs.
