Are two hydras 26 enough for this tank?

Hello guys, I'm riding a 51 'long tank for soft corals, I'd like to know if using two Hydra 26 units would be enough to keep soft coral, the depth of the tank is 17', thanks

I have 2 hydras on a 48” long tank that has sps/lps. Soft corals wouldn’t be a problem I would not think.

IMO you need 1 hydra 26 for every 2 feet, give or take. So you cutting it close, but not really. You could increase the intensity a bit, and that might be enough for you to have corals, depending on what you want for corals. But I think you should be good.
