hi.. i have a question about photoperiod?why is it that some people keep their lights on for X amnount of hours versus Y amount.. wut are the advantages/disadvantages of keeping on lights for a long period of time?(9+hours) any comments or additional questions would be awesome.

I run my tank for 9 hours a day on the main display and the rest of the hours is run on my sump. I don't know why some people use different photoperiods, but I do believe fish need a certain amount of light per day to process vitamin D. I learned that from somewhere(LOL) I guess the amount of light per day will all depend on the inhabitants of the tank, but usually 8-9 hours is most popular from what I have seen. HTH

You also need to consider type of light vs animals kept. Stronger light like MH only needs to be run a shorter period of time each day depending on the needs of the animals. This can be anywhere from 6-10 hours a day. With less intense reef lighting like VHO/PC/T5HO, you will often end up running them 10-12 hours a day.

The combination of circumstances is often what dictates the photoperiod. You might also find this of interest...
