That time again....need suggestions.

So it's time to replace my bulbs again. I am running a current sunpod with 150w hqi's. I have been running pheonix 14k's and have been pretty pleased. I do however notice that around 8 months on mine that algae picks up and I start losing growth and color in my corals. I have been thinking about switching bulbs for a while now. I am looking for the best combo of color and par. So far these are the bulbs I am looking at....
Radium 20k
Aqualine 13000k
Pheonix 14k
Keep in mind that right now I am not having to run my actinics and I kind of like it that way. Does anyone have any experience with the aqualine? How will the life of the radium be compared to the pheonix? Par? Any help or suggestions are welcomed.

 

Do you have HQI or mogul?

 

he's got 150w HQI's

 

so heres the deal:
My guess as to why your getting algae at 8 months is because they are only 150 watt... what is the depth of the tank?

The radiums will be bluer than the phoenix 14k you have now but less PAR than the phoenix.
The phoenix 14k will have the most par out of the three you listed above (means best growth)
the aqualine 13k is actually a more white bulb than the other two. It has slightly lower PAR than the other two though, and the spectral plot isnt anything fancy...

I would say stay with the phoenix for the decent pop and fair growth, or else suffer slow growth and go with the radiums for awesome color...

 

The tank is a standard 125g so it is 22".
