Light Pro's --- ATI 4x24

[Reeferguy34]

I have a question for you light pros out there. I have a 20"x20x20 Solana. Currently I have a nova exteme pro 6x18w t5. I was considering changing to led but decided I wanted an ATI. I am planning to start keeping Sps/mixed reef, do you think the 4x24w sunpower will be enough or should I go with the 6x24w????

6 bulb would be ideal

Another vote for 6.

6 bulbs for sure. 4 bulbs will not cover the tank. The widest I would ever use a 4 bulb fixture for is 14-16". Once you get to the 18-22" range you need 6 bulbs.

Not to mention that you can do so much more with 6 bulbs than 4. 4 bulbs just limits the combo way too much.
