calcium question

[Timmy's Marine]

My calcium is sitting at 400 at this point. I know that this is within the safe range, but should I start thinking about adding to it. We don't have a sump/fuge so we do water changes changes every two week (10g out of 72g).

And, what would be the best way to add calcium without a reactor?

I drip kalk...seems to work well ...

Ditto on the kalk. I dose through an autotopoff and it keeps my Ca and Alk balanced.
