    Thanks for info Mark. It will be a great help in following threads, even thoughit is rather like a Phisics lesson. Mike (Dogsbody)

    Yeah, good idea! well helpful, dont know if it's worth adding measurement/ volume abb's for pond construction and alike. May be a conversion table too? Guess many people have them on their phone these days??or it's already in a different post

    Thanks for that Mark, do you think it would be worth mentioning that PPM is the same as mg/l for most purposes?

    A couple that had me stumped for quite a while:

    TPR = tangential pond return (i.e. enters the pond at an angle to the wall)
    PPR = perpendicular pond return (enters the pond at 90 degrees to the wall)

    I've also seen GPR = still don't know what that means?
