Pond Boss Forums MANAGING AN EXISTING POND Fertilization Question about phosphorous?

What are the current guidelines for phosphorous and pond management?
Will to much create algea or is that Nitrogen? A friends pond has 6 ppm phosphorous, what should he do?

I don't know but would like to. I'm planning on putting out a bunch of phosphorus in a week or so to get some plant going but don't want to get my pond watrer out of balance.

I'm not too keen about using alum so I'm going to try Phoslock to remove phosphorus but my pond is only 1/4 ac.

I would personally use the alum/hydrated lime (50%H by weight) to remove P. Alum binds with P and produces aluminum phosphate making the P unavailable.
Edit: Total P > 0.03 ppm will increase plant growth and eutrophication.

I question the test accuracy of 6 ppm of phosphorus in a pond. Even total phosphorus (soluable and bound) should not be as high as 6ppm. It is not likely but not impossible.

Bill do you think he may have a false high due to some kind of run off from all the rain that has fallen in Ga. Lately?

You sure that is not a soil test ?

Travis, look in the current issue of Pond Boss Magazine. Good article there.

IIRC 1/2# of P can grow 500# of FA.
