    Yes you can have to much light for your corals.

    I would say that 3 175s + 4 54 watt t5's is more light than you need in a 75 gallon tank, but you need to list what corals you want to keep. Lots of sps corals and clams on the bottom you might be ok, but if you want anything other than high light sps in the tank, you will have to make some ledges to shadow them.
