Like above, I'd get a Blue Plus and either a Coral Plus or Purple Plus depending on what you need them for. Here's the quick breakdown between the 2.
Coral Plus:Combines the properties of a Blue Plus (~50%) + Aquablue Special (~40%) + Purple Plus (~10%) producing a bulb with an approximate color temperature of 15000K+. Appears cool, crisp white to the eye.
Purple Plus: Combines the properties of a full spectrum bulb with strong red and blue components producing a bulb with excellent color-rendition that works very well for bringing out the pinks, purples and reds in an aquarium.
