Hi Houman,

When it comes down to deciding between the Mitras LB Ocean Blue or LB Actinic, it is really a matter of overall color preference. Judging from the photos, your friend favors the bluer spectrum.

In order to fill the spectrum gap, he would benefit from using either one. If he has a Profilux controller, he will have full control over the Light Bars. In which case, he can tune the Actinic model to suit his desires.

The Mitras LB 70 will cover the front to back of his tank.
