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 (I believe). Lights are mounted at 21cm from the lid per book recommendation. Any tips how to master PAR measurements and if I should make any changes to my settings. At the moment I have zoanthids and anemone.

You will need a par meter to measure the light intensity at different locations to create an illumination intensity “heat” map

Could you give me some recommendations which meters are worth to buy?
