I'm not sure lighting longer just because of the reduced par of not having actinics would be the sollution, I'm putting a lot of light in the tank with the 3ea 400w 14k DE halides no?. I'm willing to try though. I have the retrofit T5's I intended to use for Actinics but I haven't gotten around to installing them yet.

slow groth is not due to the lighting and the higher the K your lights are the more itinics light spectrum they have normaly I have seen 14k's that are yellow. but mostly they tend to have a itinic color or blue color.

I would look at the Mag and CA these are the primary bulding blocks for calsification.
