Daily Light Integral

[terracereef]

Can anyone tell me what the DLI range should be for SPS dominant tank?

Thanks

Interval? Natural light near the equator is roughly 12 on 12 off. Intensity changes at the beginning and end of the photoperiod. I think @Dana Riddle may have a better, non generalistic idea to provide you an answer?

Summer DLI (sunny) – 10 feet – 33.7, or an average of 780 µmol photons·m²·sec
Summer DLI (cloudy) – 10 feet – 22.9, or an average of 511 µmol photons·m²·sec
See Figure 18.

300 ppfd for 12hrs ...dli is approx 13.

Reality is 5 to 6 hours full intensity the coral absorbs all the light it's going to. Counting overcast mornings and cloudy days corals never see 12 peak intensity daily once you are factoring in sunrise and sunsets. So the longer you light your tank the less intensity you can use to balance out your lighting. Electricity expensive where I live so I light UV 8 hours 15 minutes blues 7 hours and whites 6 hours.

OP - I would encourage you to take some time and read the article linked by Oreo (Dana's). You may have already, or you may already be aware of DLI. If not - it is a great read a couple times. That is if you are interested in running it.

On the other hand 99% of the hobbyists do not and just run their lights and respected schedule as they see fit.
