My BIL was using the carbon filter to remove the chlorine in his fill water
and ended up killing one fish and severely stressing two others. I would
recommend that you have a chlorine test kit and use it at the beginning and
end of any significant water changes. We tested the water in front of the
filter and behind the filter, and I don't know how, but the reading after
the filter was higher (like swimming pool safe) than in front of the filter.

I add my dechlor directly to the pond during filling. After you have
done
it a few times, you know how many of those 30 gallon cans it takes to
bring
the water level up one inch or two inches. That gives you a good idea
of
how many gallons of water you will be adding. Then add approximately
the
appropriate amount and you will be more than fine.

After six years of randomly pouring in dechlorinator, I finally timed
how long it took to fill a 4 gallon bucket with the hose. Then leaving
the hose running at the same force, I timed how long it took to replace
pond water. Before filling the pond, I guessed at how long it would
take, poured in a corresponding amount of dechlor. and set a timer for
that amount of time. When I checked and the level wasn't even halfway to
where I wanted it, I threw in more dechlor. and set the timer again.
After having done this once or twice I know how long it takes when the
pond is at certain levels and can put in more than enough dechlorinator
at the beginning.

I'm also still using the chlorine removing carbon whole house filter,
but the declorinator makes me feel safer (it's a combined product with
minerals and "stuff" for the koi).
