Oh, I should mention I use Kent salt for the higher Ca.

the only thing that will be different is the rate at which your tank drops as you have observed your old tank had a very low requirement so the drop was very slow, once you raised your Ca requirement with fuzzy sticks and a clam it sped up and became more apparent.

just out of curiosity what is the Ca level on fresh Kent mix?
