redsea 90s

Hi everyone, I’ve recently bought two Red Sea 90 lights for my tank. I have 326l aqua one tank with dimensions: 120cm (length) x 55cm (depth) x 53cm (height). My question is how to create and understand PAR parameters. I have 45% blue and 10% settings. Lights are mounted at 21cm from the lid...

Just curious what others are using for settings on their Red Sea 90 lights. I have 2 over my Red Sea 350 mixed reef tank. I have some SPS at the top of the tank, so I want the lights to be strong, but I also have some lower light corals at the bottom… (75-150 par target) I’m fighting the urge...

A pair of redsea 90 for $500 or a single for $300 Shipping is $20 buyer pays
