Question 55g tank with 550watt lighting system good or bad????

i have a 55g tank that i have set up. it was a mature tank before. i had it running for 8 months. now i moved so i reseted it. i came across a douldble 250watt lighting system so i bougth it. now do you guys think that the lighting is going to be an overkill for my tank. i am trying to set up a all sps tank.(500watt is the total lighting not 550watt)

Mine are 8" above the water. If you run a higher par bulb, I would raise it up a little. What bulb and ballast will you be running ?

I would, it will get water splashes at the height. Not good if your running SE bulbs (DE bulbs requires UV glass shield). It really depends on the light reflectors or pendent your using. Some have greater light spread and will spill light into the room instead of your tank.

ultraviolet the DE bulbs don't have a second layer of glass to shield from UV like SE do, so you have to use a tempered glass shield to reduce the UV entering the tank.
