photoperiod

Hello, I recently got an XR15 pro gen6 and I’m working on a template. Right now, I’m using the phx14+ spectrum, but I’m having a bit of trouble deciding between two options. Should I have a peak intensity photoperiod of 2 hours or should I have a sinusoidal period with a peak intensity that...

Hi Everyone! TLDR: Enjoy this Reef lighting DLI made simple calculator I made to make choosing your lighting settings easier. Target DLI over SPS of 10.5 (7-12.5 range) DLI, and Target DLI over LPS of 5 (2-7 range) DLI. So I went down the PAR & DLI rabbit hole because I haven't been 100% happy...

I've been doing some reading about running more than one photo period in a day. It sounds like this substantially increases growth rates, and with the tank set to run fallow for 12 weeks once I've caught all of our fish, I think I have a great window to experiment with a lighting schedule that...

I just had a random thought/question about lighting and please correct me if I’m wrong: Let’s say that your tank’s chemistry/flow and everything is on point. Will having a longer photoperiod of LEDs that don’t have the best PAR/PUR do the same as lights with high PAR/PUR lighting that is only on...
