Turn off filters for adding calcium and alkalinity supplements

This might be a dumb question....When adding calcium/alkalinity buffers, do I need to turn off my canister and emperor 400 filter and protein skimmer? I sometimes do and sometimes don't. Do these have the capability of filtering out the effect of the supplements? The reason I ask is I have been adding calcium buffers every other day or so and I can't get my calcium to 400. The closest I get is 380 or so.

380 is not that bad. Maybe mix it in your PWC water or top off water and then add.

Mag should be about 3x Ca. Raising Ca reduces Alk and all 3 must be maintained in balance. That's why there are so many 2-part solutions available.
