Light times

I have a metal halide 150 watt 14k light. Right now I am cycling my tank but I was wondering how long I should have the light on for and what times are the best?

Do you have LR in the tank yuo are trying to get coraline going on? If not no light is really required for the cycle period. If so and 8 hour period would be more than enough. You do not want to provide too much light early on as this may only promote unwanted algea growth.

Welcome to AquariumAdvice.com!!!
Phot-period during the cycle is not much of a concern. In fact, limiting it may help with algae and diatom blooms durning the cycle. A couple hours a day will be fine.
Some people are like slinkies...they serve no real purpose yet can still bring a smile to your face when you push them down the stairs!:p
Have a great day! Brian

I agree with the rest.
Age is relative, you are only as old as you act....of course, this works in reverse....

Questions loved, heeded advice greatly appreciated!

I agree also if you are just cycling you can help yourself out by only running them a few hrs a day. Cant wait to see your tank
