I have been having Ca troubles for quite sometime now. This past weekend I
decided to test Mg and it was quite low ~800 ppm... :o

Started dosing Mg tonight, Tech-M. The instructions dictate 1 ml / gallon of
water everyday until you reach the target amount of 1250-1350 ppm. (This
will raise the Mg 39.1 ppm / day it says)

My question is, does this sound right to you all? Dosing 30-35 ml per day
(for 30-35 gallons of tank water) seems an aweful lot. Or am I misreading
this? (has happened before :D )

Best regards,

Rick
