Hi,

I have the tank in my signature: 60G (230L), 40G (150L) real volume measured
I use a Giesemann Gallery of 4x54W in T5

Some here advanced that it could be too much light using T5

I actually suspend my lights at about 4in (9-10cm)

How far should I max it out to stay in a high light setup without being in a too much useless high light config?

Many thanks for any feedback on your own expierience
