How many Radion G5
 

Hey,

I've got a 500 gallon tank PENINSULA style, mostly sps
The tank dimensions are 84"x48"x30" I also have 4 72" Reefbrite XHO 2 are blue 2 are 50/50 white blue. In trying to figure out if I need

2 rows of 6 xr30
2 rows of 8 xr30
3 rows of 3 xr 30

3 rows of 5 xr15
3 rows of 18 xr15
2 rows of 6 xr15


I'm thinking about the future version of major colonies. Any help would be appreciated. Thanks folks

While I don’t have a tank near that big I watched a brs video that suggested using xr15s over xr30s because you can get a more even spread of light with the two light sources being separated. Of your options I think to start the 3 rows of 5 xr15s would be best. You can also always add more xr15s if you think you need more later
