  1. ID please ?

    Picked up a few Acropora SPS corals and want to know more about identification? Does anyone recognize and/or know the Id ? Perhaps origin waters? Seller didn't have this information.

  2. Graphs

    Yesterday I posted up the latest water parameters from my tank. Here are a couple of graphs to show how the Aqua Controller tracks some variables.

    ORP: I've been dosing Hydrogen Peroxiide (3%) each morning, so the ORP rises sharply and then drops down over the next few hours. I'm dosing it to kill dinoflagellates, and that dose is 1ml per 10g actual water volume. This is done daily for 7 days, and today is the last day. It appears to have worked.

  3. reactor vs. stand alone doser

    i keep a mixed reef. 90g display with approx. 40g. sump. minus the LR it's about 100g.
    for years i have been dosing the big 3 manually and now with a SA doser.
    i have never used a reactor and i am curious to how difficult or simple they are to use?
    even with the stand alone doser, i need to test and adjust on an ongoing basis.
    would this be the same with a reactor?
    not really sure how they work?
