20K XM versus 12K reflux question

[mr_anderson]

I currently have mostly soft corals and LPS in my tank, but i also have a few SPS (monti caps, green slimer, purple millie) and a corcea clam. Do you guys think the 20K XM would be ok for them to grow nicely, or should I just stick with the 12K reflux. I am not using any supplement actinic lighting and dont think the 12k reflux is giving my softies the spectrum it they need to grow.

I switched from 14k to 20k and I saw faster growth. I kept sps lps and clams.

I switched from an XM 10K to the 12K Reeflux...I love it. Great color and nice growth. I have an XM 20K on my wifes tank...too dim/dull in my opinion.

Crazy4salth20 can you give more thoughts on your switch such as brightness, difference in color, which had better growth?

The ballast plays a big role too. Like Crazy4salth2o said the Reeflux 12k looks nice! . The bulbs burn really nice on Coralvue ballasts so just a thought.
