Reducing light period

[chauwall]

I want to reduce my lighting from 12 hours to 8 or less. When reducing, do you reduce both actinics and full daylight or just daylight and keep actinics at 12 hours? Also, what is the min. photo period needed for SPS?

Thanks.

Hey Charlie! So back in the ATL? My birdsnest and zoas are doing great and pretty huge now. BTW, the BN looks exactly like my tubs, not pink. Is it a tubs or do BN grow differently in different lights?

Anyway, thanks for the tip. I just changed to the photoperiod with less daylights but not really sure if actinics count. I have 6 bulbs of T-5s.

I would just reduce the daylights and let the actinics stay on. I would say the min for sps depends on the intensity of your lights and requirement for the coral but something around 6 would be a bare min with T-5s.

depends what your trying to do though, your reducing your photoperiod, for what intent? you think your corals are getting too much light? trying to help out on that power bill? fish have bags under their eyes and need more sleep?

Ha,ha! Just trying to get rid of HA-figured it will help.
