help with 2 part alk/calcium additive

[tzenda]

is it ok to add more of one than the other.

i have been adding a bout 20ml of both to a 75 gal reef along with a quart of (1tsp kalk 10ml vinigar 1gal water) kalk every night and my calcium level has gone down to 195 from 225 in two weeks while my alk level has stayed the same at 3.5meg/L

all i have in there for coral is frags of a branchin hammer (1 inch round), kenya tree (about 3 inches tall), candy cane with 8 small heads, and 2 one inch peices of acro.

should i bump up all my additions, or just one, or what,
any suggestions??

btw, every thing looks like its pretty happy except the acro its supposed to be purple tipped but its not.

if you add Kalk too quickly it can precipate calcium out of the water column

Have you tested your water for calcium to see exactly how much you already have?
