There are several methods to control/curb algae and a siesta period is one. It may not be the best but it does reduce the growth. I am only stating several options and didn't mean to suggest it was totally necessary.

Fluorescent tubes: linear tubes experience cathode tube decay over time and the spectrum can shift and the light output drops off dramatically. I believe the Interpet Triton tube claims theirs is the same until it goes dead; althou I haven't seen any data to back this up.

The T5 technology in CF/PC tubes enables them to be effective for twice as long but they have the same issues as the linear. So if you wish to have the same intensity of light and the designed spectral output change them out.
