Need opinions on Bulb Change?

[FrankB1]

I currently use a 250W 14K DE Phoenix bulb over a 20 Gal long SPS/Clam tank. In the past 8 months the SPS frags have colored up Ok but growth has been decent in a couple frags while nearly no growth in others like a blue Acro.

I'am considering switching bulbs to a 10K Aqualine Buske. Any opinions on this bulb. Looking to stimulate some growth over the next 6-8 months.

Other water parameters have been good.

Ca 450ppm
Alk 8.0-8.2
pH 8.3 (although pH swings down to 7.9 even with sump light over Chaeto algae at night)

temp 81.5
Salinity 1.026
Nitrite/phosphates 0.0 ppm

To answer this question correctly we need to know your ballast manufacture.
