To Mount a light or not Mount my light

[msp3]

I recently mounted my 36 in nova extreme light today and noticed much more light outside of my tank then when I had it laying on the lips of the tank. I also noticed one of my acans not fully extended like it usually is. Did me mounted the light have something to do with this. The light is T5 39x4.

What size tank?

Was it on top of the lip or does it have legs?

40 gallon and it was just mounted on top of the tank with a glass top but now its mounted on legs.

I would keep it on the legs to get as much oxygen exchange as possible. I would give your acan a couple days to see what happens, if you think its the light you can move him up a bit in the tank to make up for the distance.

Yeah I guess it was me being paranoid, Now what do I really do when I gotta leave my tank for a day with the mother in law. Do you guys think everything will be okay? Any tips will be greatly appreciatied

The extra height is nice, keeps the tank from getting to hot and get nice spread of light. You can always build a canopy to keep the stray light from being annoying.
