    For a short time I had been trailing varied amounts of dosing and temperature to try out phosphate precipitation to cal-phos.

    The levels that were tried and tried again differently each time eventually worked and what I believe to be the precipitation of phosphate from the waters binding to calcium came on very strong and phos disappeared from the tests.
    I had tried a GFH then pool starver to make sure of phos control as I use algae for that type of thing.
    Then the tanks were on their own with quite a lot of over feeding beyond the usual to get phos beyond 0.03.
    I used three different tests to check as it went along and the none extended precipitation on the glass, plastic, everywhere! certainly came on strong.
    There was a multitude of standard extended or spiky you might say cal precipitation as well, but that was a given with the types of dosing I was using.

    At the end of it all i scraped and crushed a few of the thousands of what looked like coralline with no colour, off the walls taking it back with the use of co2 in a cup of no phos tested RO water made into saltwater.
    It didn’t loose its colour, it never had any!
    In that cup the tests of phos were near off the charts.
    It certainly works, but I lost a few sps, some acans changed colours, most decorative algae melted away, some cal skeleton inverts grew faster then I could imagine including clams and others showed their detest at what I did to them as the pic that follows shows quite clearly.
    Need less to say, phosphate removal is best done in one of the many other purchased or natural ways available.
    Making calcium phosphate your self is not in your reef life’s best interests!

    In that short time of dosing water torture, this sps changed in shape from normal to show it’s hate of what I did to them by giving me the finger, three times just to make sure I got the message.
