    Hi reefers.
    Please could you advise, there is so many conflicting articles on the use of NP pellets in conjunction with a phosphate remover. Some articles say you cannot use a phosphate remover with the NP pellets. Others maintain you can.
    Particularly when used in a LPS tank.

    Obviously water parameters have to be monitored carefully due to it creating an LNS system.

    Those that have had any experience with the following.
    Please advise.

    The problem with running them together is the fact that the pellets remove nitrates and phosphates as per the redfield ratio. Now if you add a phosphate remover you could prevent the NP pellets from removing nitrate. And also vice versa.

    So you could either be left with an excess of nitrate or phosphate. I believe that only after one of these parameters are 0 with running pellets, should you add a reactor to remove the element that got left behind.

    In most cases its the phophate that gets left behind since the ration is 16:1(N:p). And this is why some run a phosphate reactor.
