I've a rimless reef aquarium without canopy, using an ATI Powermodule 6x54w T5 fixture. You can see some pics in my blog (it's also in english, in spite of I've to update it soon).

I'm thinking to supplement this with a LED bar in order to get the desired shimmer effect, not only for moonlight. The size of my tank is 120cm x 50cm x 50cm. What do you think it's the best option without fix it to the fixture, just put it over the tank?

Thanks in advance by your support. ...
