Subject: [APD] Simulating sunrise & sunset in Aquarium Lighting

Hi! All,

I have a 90 g planted tank which has 210 watts of PL lights controlled
by a digital timer. Was wondering if it is possible to simulate day &
night using the same light. This would be better for the fishes as
compared to all the lights coming on at the same time & all of them
getting switched off at the same time.Is there any device available
using which the lights can come on slowly simulating sunrise and then
swich off slowly simulating sunset?

Thanks is advance for your resposnes.

Regards,

Saugata

Compact fluorescent lights (or PL lights as you refer to them) should
not be dimmed.  The bulbs do not take kindly to being under driven.
