Thanks George

Surroundng plants are mainly evergreen & light leaved bushes. One point of
possible concern is a Laburnam. Now I know they are poisonous, but how
poisonous to fish?


I hope this doesn't come too late. Laburnam contains cytisine, which is a
highly toxic alkaloid, causes nervous sytem paralysis in fish, and is toxic to
most other animals as well, including people. My recommendation? Lose the
Laburnam.

I live in the south of the UK & I want to construct a second pond, which
will be stream fed from my first pond. The first pond is in direct sun
for
most of the day & has lots of wildlife inc' great crested newts & a
couple
of grass carp, but the second pond will be in dappled shade & surrounded
by
thin bushes & small trees.

I intend to dig it to about 1500 gallons. Predominantly I want to stock
medium size carp, maybe koi's, orfes & tench etc..

Will the lack of direct sunlight be too detrimental to the health of the
fish & what other concerns shold I consider?

Thanks

Not at all, unless you want to grow water plants in the pond, which may
pose a
problem. Another thing to consider is the type of shading. For instance,
if
you place the pond in proximity to deciduous trees, expect to be cleaning
leaves
and other material out of it quite often. It would probably be better if
the
shade plants were evergreens instead, since they produce less material
that
would end up in the pond. Other than that, go for it.
