CoralLife Seascape 48" on a 55g

[FishyThings]

I just bought this CoralLife Seascape for my 55g its 21" tall 12" wide and 4' long
I was planning to only have lps and softies in the tank
If the light is not strong enough I was wondering if two of these on each end would work out: AND if those dont work then I would go with a black box probably a Phlizon

I would run the light at max settings to get as much par as I can out of it

At only 23 watts, it's a fine fish only fixture for a 21" tall tank. IMHO it's very iffy for coral health and growth. Two units will not be a big improvement. The issue isn't the amount of light, but the penetration into the water.

Consider 2 Mars Aqua leds or a 32" Viparspectra fixture. Lots of reefers here use them.
