    Commercial products contain magnesium chloride so no harm in using it. I've been using food grade magnesium chloride for years.

    Hi @ 459b so does not effect the coral n fish
    so my thinking add 1 teaspoon for every 100 litre of yr reef tank seize in 2 litres of RO water letting it dissolve and add to sump
    you think it's a better method to raise magnesium levels

    One teaspoon per 100 liters is nothing, I'm adding around four teaspoons twice a week to 400ltr tank just to keep levels in order.

    According to Seachem...use 5g per 80 liters twice a week. Dissolve in at least 250ml of water

    Use the online calculators to determine how much to dose. You cannot dose what another person with the same tank dose because each tank is different.

    You can use that calculator. Just remember to always dose slowly over a week or two, not all at once. Not more than maybe 30 ppm a day.

    i agree here, while water capacity will be the same your demand may differ from davids, due to stocking differences, i know david loves his sticks lol

    I do agree with leslie as well it's just I have used calculators etc in the past but what usually worked best was finding someone with similiar conditions, using their methods and then just testing and adjusting according.

    i think most calculators take bare water capacity into account if im not mistaken we then need to assess what demand our species kept put on the system and then adjust mostly up to acomodate,

    softies i think are pretty straight forward but lps and sps can grow very fast and suck a system dry of elements quickly
