GreenStuff said:It's been doing this for over a year now. There's nothing in the tank that could cause it rise, so I've always blamed it on a half of a small bag of Hagen substrate that I mixed with the Flourite when I was doing one of my major cleanings. So I just have to deal with it. :-(

Huh.fishface said:why is is that you wished you had not added Mg? i also have super soft water and used to add crushed coral to my canister but i quit...just put it in again last night though.
is there such a thing as general "optimal" target ranges for kh and gh for your average planted tank? i know that kh is relative to ph regarding c02 levels but otherwise?m lemay said:because it gives me little control over GH/Kh.
At one point I had an Mg deficiency because of my oversight of thinking Gh was in the bag. I began to add Mg at water change and the deficiency symptoms went away.
