Nope I have never used
copper in the tank. I have a
copper test kit for treating my
QT and I checked the
copper level in my
DT to be sure its 0. I still haven't gotten around to testing for magnesium so I have no idea what its at. I dont dose for it though, all I'm using right now is Kent Marine 2 part. I need to get around to getting that magnesium test kit, but so far my alkalinity and calcium levels are pretty stable.
