So I've been looking a controllers and I took a program language class a decade ago so setting one up diy is out of the question. With that said I was wondering does anyone have experience with the apex par meter? I would rather get a reefkeeper since cheaper but I can't find one for that set up. I want to use for setting up for par readings, so I can know exact measurements as well as store data so I know when the light is losing power.
