How long do you guys run your photoperiod

[MikeEe]

Currently I have it on for only 6 hrs a day due to the hot summer. My colors are okay, but could be better. Would increasing the duration improve color and growth? Thanks -Mike

12hrs on two and 13hrs on the third.

I run 10hrs in the summer and 11hrs in the winter.

 

[MikeEe]

looks like i need to bump up my photoperiod. Has it been proven that longer photoperiod increases growth? Seems logical. How about color?

 

[trueblackpercula]

Actinics from 10 to 10
halide from 12 to 9

Do you feed your SPS? This will also help w/ your color problem . I feed everyday .

I feed about twice a week with phyto and oyster pearl. Do you turn of your skimmer when doing so?

11hrs mh no supplement

fyi phyto won't feed your corals, it's too small, although it does feed other stuff that might feed your corals.

But if you have a small photoperiod due to the heat I'd stick with that, since its easier to get something back that lost a little color than it is to deal with high temperatures. Also you might try a reverse photoperiod (ie lights on at night when its cooler) although I wouldn't recommend this to anyone if its not really dark in the room with the tank during the day.
