12" tall, 23 gal cube: how much PC for clams?

[pjr]

Hi folks... I'm considering the potential to turn a 12" tall cube tank (23 gal) into a small clam-only tank. I'd add some live rock, and maybe a clown as well. My question: how much PC light would work in this setup for clams to thrive? I have 2 sqamosa (4"), and three juvinille clams (1.5" max, 2" corcea. 2.5" deresa).

I was thinking of using a 2x55w PC setup. One 6700K, one 03 bulb. Thoughts? Thanks!!!

I would go with intensity. 1 X 175 or a single 150 hqi de. Might cost a little more at first, but it's well worth it. GLITTER LINES!!
