ATI bulb order.

[Hog Head]

I made a 4 bulb 60" T5 fixture to replace my 72" Maristar. I have 2 Blue +, 2 Coral + and 1 Purple +. I am going to start with:

Front
Blue+
Purple+
Coral+
Blue+

If it's too dark I will replace the Purple+ with a Coral+, I just don't know which order or if it even matters.

Blue+
Coral+
Blue+
Coral+

Or

Blue+
Coral+
Coral+
Blue+

Opinions? Tank is 18x18x72 and is a FOWLR right now.

How blue do you want it? Ati has a good recommendation on their site. They have three color temp profiles. I didn't like the purple plus, but I don't like purple really. I have 4 blue plus, and two coral plus on my tank.

I have coral + and blue + in the Maristar now and I like it. I quit using the halides last year so the 4x36" bulbs are a little too dark. I am going to give the purple a go, it just depends on how dark it is. ATI recommends 2 blue + and 2 Coral + to stay in the 12k to 16k range. So which would be best, both coral + in the middle or every other? Thanks

To help eliminate any confusion about this post, I am asking about the arrangement of the bulbs in the fixture not about ordering new bulbs. I already have the bulbs and am just seeking input on how to arrange them In the fixture.

For 4 bulbs, I don't think it matters as long as it's not all on one side. They're extremely diffuse light sources and by the time it hits the water they're already blended.

Thanks. Appreciate it.
