How old is your tank? The par is low, but it could be something else. Are the corals stretching towards the light? If so, the tank needs more light IMO. I run T-5’s not LED’s but if you do decide to add a light, make sure you acclimate slowly. Are you sure there isn’t an irritant in the tank bothering the corals?

Yes it looks like the zoas are stretching for the light.

Yeah mate how big is the tank? Those par reading also seem low. Zoas are one of the least light-hungry corals and if they are reaching up for more light, I'd think you can use more light.

If a tank is big enough for the tangs, then id think 2 prime is too few.
