Hi,
I am currently building a 1100 litre freshwater high-tech planted aquarium. Exact dimensions are: 240cm L x 65cm W x 70cm H.
I intend to use GHL ecosystem to run the aquarium including Profilux 4, water probes, doser etc.

I now need to decide on the right choice of lights. Would 4x LX 7004 be sufficient or should I rather go for 4x LX 7006?
Aesthetically, I would not like to go for more than 4 units unless everyone would think it would be essential ...

Can you please advise?

Many thanks!
