Mimicking Natural Changing Photo Period

[Matthew5664]

When ajusting timers for daylight saving do you take into account the hours of daylight are longer in the summer than in the winter?

Meny tank reviwes I've read have a set photo period aposed to a seasonal changing one?

I ask this in relation to the spawning of fish and inverts because I've read that seasonal changes in light and temp can effect this??

There are light controllers and system controllers that mimmic photperiod and temp seasonal fluctuations, they can get quite spendy though. You are correct though, temp and photperiod changes are key contributors to spawnings in many ocean inhabitants.

Not only dayly photoperiod but the lunar cycle aswell. the length ofdaysin the tropics doesnt change much at all, but I'm sure that you can find a table of daylength for the tropics if you google hard enought, however you should not change your timer for daylight savings time, animals tend not to like it when the day arbitrarily shifts foreward or backward by an hour, I tend not to like it too, time in the world is static, we should be trying to emulate that rather than to trick things into being an hour earlier.

My tank timers are static. THe fish and inverts dont know what daylight saving means so its best not to u pset their routines.
However; I personally wouild not encourage your corals tro spawn etc as this can cause massive protien/nitrate spikes to the unwary and in an enclosed system this could cause more damage than good for your tank.

You could go all out and buy an LED lighting rack to go over the tank. They mimick clouds passing, storms, etc. but cost the earth and are still in development.

Sounds good though, to be able to pass a few clouds over your tank every now and then.

I agree with Nav, my lights will come on at the same time year round, if the fish aint happy they can
change the timers themselves
