T5 Light

[The Duke]

Hi. I have finally found a unit to fit my aquarium, my dilemma is do I go for a single T5 unit or one that would support two T5 bulbs? My aim is to have it quite bright and grow plants. The tank is 100 litres 31"x18"x16". Any thoughts on what would be best?

Are they 24w?

I would just go for one - less chance of algae

It does depend on plants you want to keep though and wheher you're dosing ferts and adding co2
