What are your recommenadtions, how fast should I raise the value...90 tea spoon sounds alot...and the label on the seachem mg container says it can impact on the Ph (lower it)..

Marco,
<EDIT>Hang on, I looked up the Seachem Reef Advantage Mg additive and it is a powder. The Kent product I used was liquid and recommended using X amount of ml of the additive. In one tank, I used 543 mls to get Mg to 1350 ppm. So I assume their calculation of using a whole whack of teaspoons is probably correct.
Also, follow the instructions of not adding it all in one day. I spread my additions over three days, adding 20, 30 or 40 mls (depending on tank size) at a time throughout each day.
