Alkalinty

Why does alkalinity decrease or increase in an aquarium?

 

[Spartanwarrior]

your corals are using the total alkalinity to build their calcium carbonate skeletons. decreases because of a higher demand aka growth. increases because of lack of growth, basically the addition is too high for the demand. the true test is to keep this number or TA at a stable value such as 7dKH, or 9dKH, etc. Fluctuations in alkalinity has shown to cause RTN/STN.
