Light good for 20 long reef?

[Paxdaddy]

Been thinking about setting up a 20 long reef tank. Would def. like to do led without spending a fortune. Would one of these work well on a 20 long? Would it cover the whole length of the tank? How high would I want to mount above the water line? And sure I would want to run it dimmed quite a bit right? So many questions! Thank in advance!

One of those will be fine. You can find them cheaper on ebay (like 80$ shipped i believe)

Ok thanks. Any idea how high above the water I would want it?

You'll want to turn that fixture way down. It's plenty to reach the bottom of a 30" tank.

That is really my only concern. Even turned way down will it be too bright? Would there be a better alternative while staying with led? This would be my first salt water tank. I know I want corals but will be starting with some of the easier ones but I want to keep my options open for down the road if ever want some harder to keep sps or something. I don't want to have to upgrade lighting at a later point.

You'll have no trouble turning them down enough.

The fixture you chose will work fine for you.
