Which one for predominantly sps growth

[Saltgarden]

Hello. For the purpose of growing sps corals which would you go with?
8 bulb Giesemann matrix II non dim vs 6 bulb ati sun power.
I’m asking because I ran both and ati is definitely cooled better but giesemann fixture has the benefit of an extra 2 bulbs and a total of 3 channels vs ati’s 2 channel.
Both units are 48” going over a 150 gallon 60x24x24 tank.
I do plan to add a dimmable led reef bar.

I haven't experienced the Giesemann fixture first hand but if I had to choose between an 8 bulb and a 6 bulb fixture for a 24" front to back tank, I would go straight to the 8 bulb. Now if you were adding an LED strip to both the front and back I could be talked into the 6 bulb.

I would go with the 8 as well. I am not really a fan of dimming T5s, but the three channels might be handy.

Go with the 8
