What brand and model for corallline algae to thrive?

[Fischer's Angel]

I am planning to start a new 55 Gallon FOWLR and would like some recommendations for which lighting system to use. I am in the tropics and it gets pretty warm here, so I want to avoid excess heat, so have decided on the standard 48" T-5.

I would like coralline algae to grow and thrive, and I am NOT planning to keep any LPS or SPS at any time - would a two bulb system be adequate for coralline?

Can you suggest which specific brand and model lighting system would work best in a 20" deep tank?

Thanks !
