Its prone to add lots of unwated materials like granual particles from
roofing etc in the pond which are relatively inert, but really shld
not be there. YOu get dust and all kind sof other fall out particulate
matter on a roof, and then having it get washed by rain into the pond
could make for problems with excessive nbutrients from pollens dust
etc......It can also inundate the pond with a heavy rainfall and
provide the fish with nothing but oxygen poor water since rainfall is
not overly rich with O2 to begin with, so it would change the
paramaters of your water much quicker in a short period of time than
if it just got what rain naturally fell into it. SOunds good to be
able to use that water for such, but probably not really a good idea.

I'm thinking of doing some renovations to our home. One possibility is to
direct the rain runoff from the asphalt shingle roof into my 650 gal pond.
My question is will the water that runs off the roof (including what it
gathers through the gutters

A. Hurt my pond & fish

B. Help my pond & fish

C. Have no affect on my pond & fish

D. Some other choice?

I'm concerned about the small pieces of asphalt or whatever it is that often
comes off the roof as it may affect my pumps and filters.

Any comment?

Thanks,
