Chemistry And The Aquarium: Solving Calcium And Alkalinity Problems
By Randy Holmes-Farley

I am in zone 3. Yesterday morning My parameters were Alk 135 Cal 360.
I have followed instruction for zone 3. Last night I got it up to Alk 135 Cal 400. It was looking great.
Today slowly tried to raise it to Cal 420, so I add more calcium.I Just test it. Now it is Alk 125 Cal 400.
What do i do wrong? Alk is dropping. Calcium did not change.
