    While there are many good articles out there on reef chemistry topics, here's a list of my articles.

    Some of them need updating, and we'll be posting revisions at R2R, but there are not many things which I think are incorrect.

    Handy Calculators (I don't claim to have written these, but they are very useful)

    Reef Chemistry Calculator

    Some more of mine. These are older and, unfortunately, just like a chemical, they apparently are degrading with time. Equations and symbols seem to be having problems, so some are becoming harder to read and understand:
