Hi,

Just finalizing my equipment for my first discus tank and I have a question regarding lighting.

As I don't like bare tanks (sorry, yes I know they are easiest) I am going to go with a very thin layer of coarse sand as a substrate. I am going to have primarily silk plants but would also like to add just a few plants that don't need substrate (i.e. anubias/java ferns on driftwood plus some floating plants) to take up some nutrients from the water.

So finally to my question. My light fixture houses 2 x 54w T5 flourescents on my 90 gal tank and I am wondering what temperature tubes other people use and/or would suggest - 5,000k, 6,500k, 8,000k? Or possible a combination would work well?

Thanks,
Graham
