You might want to just sell the marine land and pick up a full T5 set or a different LED
set. The reason is that any T5 or T8 would pretty much blend your LED
shimmer effect, and the LED
itself doesn't really make a huge differences in performance.
many people thought actinic doesn't help coral growth, and "white" bulb are the one growing coral, that is incorrect. You can grow coral with full power royal blue LEDs and they would grow like a charm. The only problem is that without the white, you can't really see the coral yourself lol.
As long as your blue LED
/bulb give enough PAR then your coral would be fine. As far as for fluorescent in coral, you can easily get the best out of them with some Royal blue LED
or violet LED
