Marc Levenson will be discussing PAR and why it matters. The plan is to cover his measurements of PAR in his own system over the last year. It will show how the bulbs have aged, since none have been changed (April of last year) since then. It should be quite interesting, both about the light at various points, as well as how the corals have responded in that time.
PAR is something that many hobbyists know little about and this should be beneficial to most reefers.
