weird Grizz I have never had a problem with my Mag, it's always up in the 1300's weird what do you think causes the mag to be sucked up so much. is your ALK and CAl going down.
ever since my tranfer to you brother's twin tank the other 96'er

I haven't check the levels , actually that is a lie i checked the alk yesterday. it was 11.6 so my Kalk Reactor is keeping up withthe CAL and ALk demand.
Hey another thing what is your MAG level at now and do you have red turf algae on your rocks.
