    Hi All,

    while i am building my new tank i have been thinking about the best way to light the tank. at 2500x1000x600 i am going to need alot of LEDs, this works out to about just over 600w worth, now what about 2 x 250w MH supplimented with LEDs?

    what is the spread of a 250w MH in those std hex units? can one get better reflectors?

    I have a 2x250W (120cm) MH over my tank which is 140 long. The ends of the tank are dull and coral colour at the ends is not as great as the ones in the middle directly under the light.

    Perhaps look at the 3x250W mh unit that is longer (2m i think), or 2 of the 2x250W (120cm) units. I dont think you will have an issue with coverage, width wise of 1000mm.

    base on what i know about your tank. It will be 3 compartments, it the seahorse and pipefish section, id say led's over the fowler/bully section add t5 and the reef sectoin do MH for groth and led for colouration.
