Are your shrimp hanging out on the glass yet?
Now it might become a balancing act like it is for me. If you see the algae starting to develop on your gravel then you know it's time to lower the light for a few days....then let it go for 12 hours again.
Yes Mr. Kamil. Will do. However, the light that we use is also a dual T5HO 24" fixture with a single 21w bulb in use. Hopefully we don't have to do a balancing act and just leave it on for 9-10 hours everyday after a certain point? Easier on the timer. I dunno...we will see!
