mag flake

[kellymm7149]

randy do you know if magflake is anhydrous or hexahydrate? I'm trying to figure how much to add to boost my IO salt mix for my water changes also how do i measure the dry flakes in ounces according to the chemistry calculator is that in volume or weight ?

It is the hexahydrate, although there may be other brand names that are anhydrous.

Magnesium chloride hexahydrate has a dry bulk density of about 0.83 grams/mL.

The calculator gives the measurment in Ounces weight for dry products like the Mag Chloride and fluid Ounces (indicated as such) for liquid supplements.
If you use liters in your volume entry you will get the result in grams instead of ounces in the vertical axis of the chart, multiply US gallons times 3.7854 to get your volume in liters.
The resulting amount on the notes at the right of the chart will give you the values in both ounces (weight not fluid) and grams for Mag chloride hex.

how i can measure the mag flake without a scale im a bit lost

I mentioned above that "Magnesium chloride hexahydrate has a dry bulk density of about 0.83 grams/mL."

So if it says to use 54 grams, use 54 g / 0.84 g/mL = 64 mL of dry solid.

If this will help you?I used 1/2 a cup of mag flakes and 1/4 cup of epsom salt to boost my mag levels.I use a brute 20 gal container filled to the top.My salinity is .26 using I/O salt.I found mag was at 1200 ppm and using the amount I boosted it to 1500 ppm.Using salifert test kit.

Although I think you may be counting lots of teaspoons :D I added teaspoons to the calculator as a unit to measure for the Mag Flake.

Hope it helps.
