When I top my pond up how much dechlorinator should I use. I top up from
the tap and our water is chlorinated. Do I use sufficient to
de-chlorinate the full pond (it is a fairly small pond), or do I just
use sufficient to dechlorinate the amount of water I am adding?
I have had a few problems with my pond recently so plan to take my pond
down by a quarter and then top a couple of times over the next month.


If you are only topping it up it's not necessary.
A Yorkshire man wasting money, amazing! :-)

The thing to worry about is if the Water Co are flushing the mains to get
rid of the freshwater shrimps, they use an insecticide and it will kill fish
too. A friend lost all his fish. They normally do it once a year so worth a
phone call, just ask them if they are flushing the mains in your area
because you want to top up your pond.

OMGosh, is this drinking water they add this to? Are people informed when
it is added?

IMHO, yorkshirespambo, you should be doing a water change out, old out, new
in 20%/week, but depends on what kind of pond you have. Koi need more,
water gardens need less... and depends on your source water, obviously...
insecticides?!!!! Sheesh. ;-) ~ jan
