garden waterfall and pond the water is not clear and i can not see my fishes - Help

Post by Friederike Fehla » Tue, 04 Jun 1996 04:00:00



We are living in Britsih Columbia Canada and have a nice back yard.  
The fish pond was very clean when we introduced Coy fishes to the pond last
week.  Now we have this green mess.   Please Help.

You might want to post your question to the rec. ponds news
group.  A group of nice people with lots of good answers. By
the way are "coy" the same as "koi" ?

Do try rec.ponds.  I am dubious about koi generally, but I imagine their
exhalants and effluvia have weirded-out the balance in your pond; it'll
take time till the bacteria adjust.

Good Luck.

Maybe the fish are so coy they don't want to be seen....? :-) Facetiousness
aside, this is quite a common problem when fish are added to a pond. The
green mess (you don't say whether the water is green or whether there are
slimy green masses growing) is caused by algae. Spores from them are
everpresent, but usually nutrient levels and predators such as waterfleas
and snail prevent them building up. However, when extra nutrients are added
the population of these algae explodes, causing the water to go green.

It doesn't take much of a detective to see that it is the koi which are
causing the green water in some way; this could be by eating the snails,
defaecating in the water and also if uneaten food gets broken down. Do you
feed the fish often? Try cutting down a little on the amount you feed them.

As far as I know, most people who keep koi also install a filter for their
pond, since koi are known to be pretty 'messy' fishes. However, if you want
to keep fish in your pond and feed them it is likely that you will have to
put up with some degree of green water. One thing - the algae do not harm
the fish, and probably help protect them against nasties like herons or
mink.

Good luck,
Tristan

There's a fellow up the road from me who specializes in ponds, koi and
the like.  He has developed a filter which is supposed to be _very_
effective, got rave reviews in the press.  I'm not interested in fish
but have some gardner friends who are and they tell me the filter
works well.  If you are still in need of info on a solution, e-mail me
your address and I'll stop in to see the expert and get you and him
communicating.

Dear Dan:

You will not be able to get rid of the algae properly until about 70% of
the surface of the pond is covered with lily pads and other plants which
will block the sunlight and consume the nutrients which are currently
allowing the algae to proliferate.  I have a filter made up of rolls of
filter medium in a large pot through which the water must pass on its way
to the pump, but right now I still also have some algae since our spring
here (Kanata, Ontario) has been so late.  However I know from experience
that in a couple of weeks the water will be as clear a brook.

So, don't worry, and whatever you do, don't empty the pond and start
again.  The new water will be full of nutrients, and the whole cycle will
start again!  By the way, gold fish and koe don't mind algae - in fact,
they eat it.

We have an 800 gallon pond and my husband built a sand filter out of
one of those ***maid containers-I think it was a 6 or 8 gallon one.
Anyway, he put gravel in the bottom then pegboard like you use to hang
tools in the garage, then screening material and finally 4 or 5 inches
of sand. Then he put a pump in the pond and connected it to a hose that
 goes into the container above the sand and another hose that connects
to the container on the bottom and in that way the pond will be free of
the particles of matter that made it unclear. We change the sand about
every 4 months or so.
