    I believe TPN+ has nitrate and phosphate added. I don't know how much and I'm not sure they list the amount. I don't believe it contains any ammonia.

    TPN contains K and the usual trace elements like copper, magnesium, iron, boron etc

    TPN+ is the same but with N&P.

    hi thanks for the replies, i know it has the normal trace etc, but was looking more to amounts and more so ammonia. i have heard it has
    "Ammonium nitrate (NH4NO3)" but not 100% sure and as to if this would have any effect on ammonia readings?

    I recall it has a small amount of NH4, not much though. I've not tested it, simply because I use bulk KNO3 etc.

    So does ADA's brighty series(some)
