    Hi Guys

    Beer time :) :peroni:
    I just want to ask if there is such a thing as too much light in a tank?

    I have a Metal Halide unit that currently has a 400W globe. (I will change it to 250W when I find a globe)

    I also have an ATI 6x24W Unit. I just connected them both onto my tank and I must be honest it looks pretty cool to me :)

    I am just worried that maybe it will be too bright for the fish and the few softies I have?

    Could I also add a smaller T5 unit say a dual globe 39W instead of the ATI to assist with colour?

    Depends on the corals. Mushrooms dont like to much light, they might shrivel up. You will have to acclimate them to your lighting slowly so they dont bleach or die.

    Maybe take a few of the tubes out in the meantime and over a course of a month add 1 each week until they all in. Maybe start with 2 this coming week, then add 2 more the next week etc etc.
    If you have been running a 400w metal halide I dont think adding 2 extra tubes every week/week and a half should be too much of a problem. Just keep an eye on how the corals are reacting or if they are starting to bleach.
