lighting for 20 gal long

[davidhughes85]

What kind of lighting do I need in a 20 long to keep clams and sps...and not just keep the sps alive but colored up. Metal Halides are not an option

If you cannot use meal halides you are going to need alot of t-5 high outputs

how much?

I'm thinking about 6 tubes minimum, that is probably as many as you can fit.

where can i get something like this?

It depends on what you have. Do you have a hood? Can you mount a pendant? If you have a hood, you can mount retrofit kits like this inside the hood.
