	Is 65w over 20g enough light?
just_one_more Hobbyist Posts: 122 Kudos: 138 Votes: 31 Registered: 31-Mar-2004	I have a 65w cf that I am going to put on a 20g tank in the future. Will this be enough light to support growth on live rock? How about corals?

just_one_more Hobbyist Posts: 122 Kudos: 138 Votes: 31 Registered: 31-Mar-2004	So the coraline algae growth is independent of light? What are some of the best sites for information on reef tanks? As I said, I will be adding the light in the FUTURE so I still have a lot to read up on. Thanks!

I have 30 w of NO flourescents over my 55, and coralline is growing just fine, all you need is CALCIUM, imo. Edit: You do need some light though, but you would have that anyway to see the fish hopefully. Last edited by fantomfish at 21-Apr-2005 20:52
