i wouldn't suggest it. since even fish need some period of darkness. just like us.also, if you have plants, plants require those hours of darkness. besides, having it on 24/7 evaporates your water quicker. so that means more water changes. hehe.
keeping your light on 24/7 will stress your fish out and dull their colors. Also you may kill them by stressing them our so much. I would suggest turning it off at nights when your asleep.
Easy thing to do is get a timer. Put in on for no more than 12 hours. I usually set mine to go off when I usually goto bed so when I home I can always see my fish.
If you are going to use a timer set it to come on for 3 hours, then off for 2 hours then back on for 7 hours,the plants will photosynthesise but the algae seems to have problems with the break in light intensity. 8)
Please tell me more of the light setting you suggest and how it helps prevent algae. What kind of algae? I dont mind the greens on the rocks, glass, its the black hair algae on the plants which I avoid.
Thanks
It is a very srange thing, but the algae seems to need about 5 hours to start growing, the break in the lighting seems to stop the reproduction cycle from taking place. 8)
