  1. Hi all, 

    Just upgraded to a 6-footer.

    Running a calcium reactor. 

    Tested the water after one week, and was shocked to find Ca level of 261 (Hanna kit).

    Couldn't believe it so did an immediate retest. Got 316.

    kH was 9.

    I've never seen such low Ca in any of my set ups. 

    Any idea what is causing this?

    I've dosed with liquid calcium, and will do a retest same time tomorrow. 

    Hopefully this is just a temporary glitch.

  2. Hi reefers. I have assorted frags and mini colonies to clear. 

    Big (colonies): $10 each

    Small (frags): $5 each (incl ultra lumi hairy mushroom and zoa)

    Reason for cheap sale: They are substandard, lost colour and polyps after spending one week in holding tank during my upgrade. (Softies are fine though.)

    They will revive in your tank if conditions are optimal.

    Take all for $20. (Priority)

    Has anyone had poor experience with Aquamarin?

    Bought an ATI set from them a month ago. They ask for payment in FULL and said lights will arrive in THREE WEEKS.

    Now, delay after delay. And they keep blaming ATI side.

    Wrote to ATI, which replied saying delay could have been caused by some public holidays in early-June.

    Very un-German!

  4. While global warming is very real, temperature rises very very gradually. And if you go out to the Great Barrier Reef, the water is still cold (relative to around here).

    So my theory is that there may be other factors - such as changing salinity and nutrient levels - that are contributing to widespread bleaching. Not forgetting natural predators such as crown-of-thorn starfish.

  5. Hi folks. As you may have read, vast areas of reefs all over the world are bleaching. Rising temperature is the suspected cause but I believe there are other contributing causes.

    Anyway I believe bleaching can be reversed, based on what I see in my own tank.

    A few months ago, my reverse sunset monti started bleaching for no known reason.

    Then it stopped. And now the coral is starting to re-colonise the dead parts. Really cool.
