Hey Grim, I'm thinking about ordering the 6 bulb 48" TEK from coralreefecosystems. They offer the following bulb selections:
Midday 6500K
Aqua Blue + 11K
Actinic + Blue
Pure Actinic


What combination would you recommend for the best mix of growth/color?

4 Actinic Plus, one midday and 1 Aquablue
 
I am looking to add one T5 bulb to the front of my tank/canopy. I want to angle that bulb towards my reef and I also plan on using it as my dusk/dawn feature to turn on before and after my 2x 250 watt radiums. My question is, which T5 bulb would give me the best combo of color and growth? I am looking for a T5 bulb that would be similar to a 20k halide like the Radium. I am thinking about going with this setup, unless somebody can recommend something better: http://www.reefgeek.com/lighting/T5...T5_High-Output_Retrofit_Kit_w!_Bulb_by_IceCap
Thank you.

Thank you.

Get that with an ATI Blue Plus lamp.
 
So I'm going to be getting a 40 breeder soon and thinking about making the switch to T5s. I was wondering if I need to go with a 6 or 8 bulb ATI fixture? It will be almost totally an SPS tank with an Ultra Crocea I have in my current tank which will be placed on the SandBed. Thanks for the help!

6 lamp ATI fixture will do fine, either of them.
 
What about the Tek 6 bulb fixture? It seems to have good reviews and cost is MUCH less... Thanks


Tek will probably be OK, just dont use the splash shield. I would grab a clamp on fan and set it so it blows across the top of the fixture from the rear, about a 20 percent gain in output doing that.
 
Ok, so is that the only downside to the tek fixture? Also, there is the sunpower and the power module fixture with the P.M. being the higher end. Is the sunpower much better than the Tek because it's only about $100 more so if it would suit me better, I would go that route...

Yeah, Sunpower will give you more PAR than the Tek even running the external fan on the Tek plus you can place the Sunpower lower because it has a splash shield so you get an even bigger boost in the amount of light making it into the tank. .
 
If you are just using it as a supplemental lamp and have room for the wider reflectors, about 3 1/4", go with the Tek.

Do you think they are about the same in regards to output and par? I don't think I really need supplemental actinic since my Radiums are already blue enough. So I figure I may as well get usable/usefull light out of my dawn/dusk bulb, as well. Thanks again.
