clams and calcium


New member
do clams use alot of calcium, i have 3 clams and a couple corals, nothing that uses alot of calcium, i usually dose about 4 teaspoons of kent marine turbo calcium everyday in a 2gallon drip doser.My calcium stays around 400, is this a normal thing because i dont want to add to much calcium but on the container it doesnt say anything about how much each teaspoon would roughly raise my calcium. thanks

calcium is only part of the story, but yes they can have a strong demand on both calcium and alkalinity. In smaller tanks, it can be a very large demand. Are you testing alkalinity as well? Usually that's the more challenging aspect to control.

+1 on the checking the alk, I used to have three clams in my 180 gallon tank, they sucked both calcium and alk up very fast
