Tropic Marin Bio cal.

[S!mon]

Anyone use this stuff? I've been using it my tank for a while now and I'm very happy with the results, but I'm going through alot. Guys at LFS say this is normal and that after a month or so I will not have to use as much. Anyone have any long term experience with this?

i have used it. i like it but i switch to bionic because its more cost effect and works. i am going to try the twopartsolution stuff next.

if you start with any of these, you need to use more in the beginning but the tank chemistry will slowly change and you use less and less to maintain the ca.
