Thats great, however Tom, and by using the same test kit you would know this, but the cotton filter step removes most particles . And if he is saying that I should be able to see the mag sediment than after that cotton filter step i could not see anything but clear water. So my assumption would be that yes some particulate magnesium precipitate does come through the effluent but two things: #1 like you said does its dissociate into the water column? right?
And #2 since ive filtered all of the mag sediment through a step in the test my reading should only be of Ionic MAG, correct?
Thanks for looking into it Tom
