there is foaming at the base.
It appears that your customer is getting nutrient influx from commercial fertilizer applications somewhere uphill from the Pond. He can't control what the neighbors do but if he eliminates the use of fertilizer within 30 feet of the pond, it will help. (Note; He can use slow-release closer).
I mentioned the possibility of Phosphates in my first post in this thread and it should be tested to determine the present level. The addition of sufficient aquatic plants should, in time, correct the problem. (It may take a full seasonal cycle). Alum based Phosphate binders are available, but are not cheap, and should be used only as a last resort because, not only will it starve the algae, it will also starve any other planting, and without eliminating the source of the contamination will involve retreating the pond on a regular basis.
Is the algae and murkiness problem seasonal or continuous, or does it present itself more strongly after a heavy rain?
I apologize for being excessively 'wordy', but there could be a combination of several factors causing the problem. Just trying to Zero-in. I also have to keep in mind the difference in climatology between your location and mine.
no apology needed. Your extremely helpful and I really appreciate it. When I was there the other day it was nice and sunny and the algea was about gone.... on the surface. On the falls its still nice and green and orange.
Looking back over the entire thread brought a question to mind. Is there a particular reason that the Koi are confined to on small area of the Pond? Carp (which despite all of the ballyhoo is what Koi really are) are notorious for eating algae and pond weeds and most anything else that they can find. They absolutely love Watermelon. Giving them free run of the entire Pond may, at least, help with a solution to the problem.
Where, geographically, is this Pond located?
Zone 5 ohio.
See thats the part I never really understood myself about the Koi. They said its easier to watch them this way I guess. When i was there the other day I saw a lone koi out in the main pond....
The algea isntbad in the koi's part,
If the Koi spawn and some of the fertilized eggs drift out to the main pond area, they will have all the Koi needed to keep the algae in control, especially if you do the aquatic plantings....the fertilized eggs will stick to the plants.
Can copper sulfate be used to control the algae? We used to use it in ponds when I was in the golf business and it seemed to really help.
Yea, if you want to kill all of the fish!..Copper is highly toxic to not only fish, but many other aquatic organisms. Golf courses do not care about ecology. if they did, they couldn't stay in business.
they tried a tiny bit last year and killed alll the amurs. So its out of the question.
year 2 and the plants are growing and nice makeover this week for the 4th!
