Nano cover

Why would you want to put a cover on your Nano for to much extra light. Is this for nighttime.

i don't get it....................

why is it covered???

are you raising young clowns? why do you have to cover it?

I know.... I know.... It's the "Stealth Nano"!

he may have reverse light cycle. he might want complete darkness during the day to help with algae.

keep light out in between lighting cycles. To really be sure i don't get unwanted algae.

What/ where did you get that wrap. I could use some for a "re-cover" of the back sections of my tank.
