ATI T5HO + RSM250

[ashr]

The Blue Plus:

Combines the properties of a Blue bulb with a Actinic Blue 03 bulb producing a unique spectrum that encourages both bluing in SPS corals and fluorescence in capable corals. Also helps balance out a washed-out/yellow hued tank. Great as a supplement to metal halides or in combination with a 6500K Sun Pro or Aquablue Special bulb

Blue Special :

Combines the properties of a Blue bulb with a full-spectrum daylight bulb producing a color temperature of approximately 12000K. Great as a stand-alone bulb or in combination with an Blue Plus or Actinic Blue 03 bulb

I'm familiar with the ATI bulbs. I've been running them on my tank for a while.

I'd personally run 3 Blue+, 2 Aquablue, and 1 Purple+.

EDIT:

Do you have 5 bulbs or 6?

[ashr]

My tank will hold 6 bulbs.s

aquablue special washes out the color of the tank.

i would go with 4 blue plus and 2 purple plus.

What do you mean washes out the tank? Please explain

Also remember I am looking for something with good SPS growth with good colours

[Mandosh]

I agree that the Aquablue can be harsh, which can make corals look washed out. They do put out a ton of par if you're looking for growth. The par numbers for the Blue+ are pretty close though.

Maybe look into the new Coral+ bulbs. They're brand new so I've never used them but they seem like they would give you the best of both worlds.

Well I think Ill stay away from the Aquablue then.. Maybe ill look at the new coral plus
