Ai Prime HD vs Dual Orbit Marine Pro

[604reefer]

Hi all!

I'm trying to decide how to light my 20g high (24"L x 18"H x 12"W). I'd like something I can control the color output to suit my tastes. I've narrowed it down to a single AI Prime HD or used Dual Orbit Marine Pro 24-36". The dual orbit comes in at 72 watts vs 55 for the Prime.

Pricing is the same between the two.

My ideal coral is frogspawn, torch, hammer, bubble, zoas, and montipora (I don't think i'll keep all of that in the tiny tank but would like the option).

What do you think?
