every tank is different on its consumption of of calcium and carbonates but I have a total volume of 180 also
I use 90 ml of Bionics two part daily to maintain a alkalinity of 10.8 dKh and calcium at 430. I haven't had to change that amount in a month now.
You should test your mag level before starting--it should be at 1300 ppm
