| As far as manufactures for the bulbs if you dig far enough you might find they all come from 2 or 3 actual manufactures so If you like the brand you had then use them. Price does not mean value.
Remember any change in light will affect the corals so you might have to drop time a little in the begining or raise the light if you can. New lights are much stronger and your corals have acclimated with the drop in lighting. |
