Just to get an idea, what are everyones nitrates levels looking like? Mine are between 10-20 ppm.... if i had to guess they are around 15 ppm. The reason I'm asking is because I would like to know how low the nitrates need to be to start adding corals and anemones. And while i'm writing this thread I'd like to know how much harder anemones are to take care of than corals. And which anemones and/ or corals are hardy, easy to take care of, and will do fine w/ a light fixture that puts out like 4 watts/gal. thank you
