    Ordered a Hanna ULR Phosphorus tester and wanted to get an idea on what levels I should aim at keeping? I know that I won't be at zero....but what is considered high that I may have to do additional water changes ...ect?

    I try to keep my phosphate under 60ppb and change out phosphate media when numbers are going up and roughly at 60-80ppb. When Rowaphos is new numbers will drop from 80 to 40 overnight.
    80 ppb = .24 ppm
    In a fully stocked reef that's normal.. my frag tank with one fish.. it runs at 9 ppb or
    .027 ppm that's normal.. check weekly and you'll know how long the phosphate media lasts before it needs changing.
    Hope you like your new Checker, and keep me in mind for reagents or other Hanna products.
    Happy reefing and happy Thanksgiving.
