What lights should i use

[rcreef]

I have a 90g cube 4x2x2 with coral and am looking to put a better light
I have a 250w metal halide and am thinking of putting some t5 to help it which bulb should i use or sould i use anothe thing

you will have enough shimmer from the Halides and enough power if you have two of those 250w bulbs. you should look into LED strips so that you can get the color you want. if not blue plus and purple plus t5 bulbs are my favorite.

I have the same tank dims and have a 10x36watt T5 fixture. It's a ton of light and I'm thinking of replacing some T5 for LEDs.
