How many Radions for a 75G tank

[Billyreef-ita]

Hi everybody,
I moved from a 40G tank to a 75G tank (48’’x20’’x20’’) with sps predominantly.
I am now lighting it with 2 X15 G6 Radion and a X30 G6 Radion (the X30 is placed in the center and the two X15 on each side).
The lights are positioned 6’’ high from the water and run at 80%.

I wonder if this is enough or do I need additional lighting to get good results for the sps. As of today I grow only Montipora but I would like to start with more difficult SPS.

Thanks

perhaps rent a PAR meter

That would be the best solution, however I cannot find anybody in Rome doing this service.

Here is a low priced option Par Meter. I use this one on my tank.

Also I won't buy Radion lights. They are over priced and under powered in my opinion. I use 4 Reefi Lab uno 2.1 with 90 degree relfectors over my 8ft 300g tank. At $480 each they are half the price of radion with better light spread thru 9 channels and more over all wattage. xr30 g6 210 wats, reefi lab 270watts.

My stylo and plating monti 1 year apart.
