do I have enough Blue?

I had the following setup in my T5 setup...
1 x 54W 6500K Daylight T5 HO Fluorescent (GE0005) by General Electric
4 x 54W Blue Plus T5 HO Fluorescent (ATI1113) by ATI
1 x 54W Purple Plus T5 HO Fluorescent (ATI1129) by ATI

I just replaced all six but got 4 x 54W Giesemann Powerchrome AquaBlue+ T5 bulbs to replace the 4 Blue Plus ATI's

now I'm thinking I do not have enough blue...

would it be best to get the 4 Blue Plus again...
have have a couple LPS and soft corals...

 

Compared to your old mix yes. The bulb has about the same look as the ATI Aquablue Special.

 

is that enough blue in general? I have a couple LPS, a couple soft corals, GSP, mushrooms and zoas ...

 

Blue is for you.... Do you like the look? With proper acclimation, corals can adapt.

 

+1,,

 

How does the 6500k benefit? I thought that spectrum encourages algae growth....

 

I used 4 giesemann aquablue bulbs in a 6 bulb fixture and ended up with decent growth, but started to brown out a lot of my coral. You might get a different result. The best thing about t5's is being able to swap a bulb or two and try a different look.

I'd use the aquablue or the GE bulb interchangeably and continue to use 4 ati blue+ and the 1 purple+.

 

Nutrients encourage algae grows. Light may favorite over another. In the past though, I've run 6500k without algae issues. If your nutrients are under control, it shouldn't really matter...
