How many LEDs???

[jerseyboy]

I am new to reefing and thinking of a nano reef about 20gal. How do you determine the amount of LED lighting required?

Are there any book or articles on this subject?

Which 20g tank? 20L? 20H? Custom?

Hi,

I am thinking 20gal but have not yet considered the configuration.I suppose a low is better for lighting purposes.Are these sold in acrylic with no frame?Is here a reference for detemining LED lighting requirements?
Thanks,

There is no easy rule of thumb, as every tank is a little different. Pick out the tank you want, and then we can figure out how many LEDs you will need.

Thanks,

Any hints on where to get a marine tank without a frame?
