Minimum light during cycle...

[amnesiak]

Hi all,

I have a couple of tanks going, but I am starting a pico. My intent was to use a small rock (covered in blue clove polyps) to seed everything else. The rock I'm using is BRS Pukani (super clean) and I'm using 'dead' aragonite sand. I will start out with nearly 100% water change water from my biggest tank. I believe my cycle will be fairly minimal.

 

What's the minimum photoperiod necessary to keep healthy cloves? The only non-DIY part in this whole setup is the return pump, so I have to share or use a cobbled-together light source while I build the light.

 

Thanks,
