    can be from the salt you used, or mistake while testing :p

    i would wait 5min, dose Ca, then 5min later add a small bit and see if it precipitates, never used seachem Ca and Alk, so its a guess from experience using others

    no need to panic about the Mg, it will come down, and at 1500 will keep bryopsis at bay :)

    why 5L? you only need to mix it in 250-500ml RO?

    you can bolus dose, pour it in, but no more than a 20ppm increase per day.
    what is you daily consumption?

    for drip dosing you can use a drip kit from a ER room

    Ca dont raise more than 20ppm a day, alk no more than 1kdH per day
    dose them 5-10min apart

    the pump will help keep stability by dosing every hour or 2

    Sorry for the hijack, if need be will open a new thread

    but I wanted to know how I would calculate dosing of reef buffer.
    I would like to control my kh levels in my tank, and wanted to use my Doser to assist.

    Anyone with some advice on how to calculate mixing buffer and how much to dose.
    Thanks in advance to anyone who assists

    first calc your daily alk consumption, then mix a stock solution as per the instructions, then dose the amount for the alk consumption based on your tank volume, spread the dosing over the day

    its on the label
