My new pond has a couple of large oak trees whose canopies hang over the pond. I've read on the forum about tannins in oak leaves, and my plan is to skim out the leaves periodically as they drop into the water this fall.

But what about acorns. For a couple of weeks now, a steady shower of acorns has been dropping into the water. Do these have the same tannins as oak leaves?

It's not as if I can do anything about it, but I am curious as to whether this will have any effect on water quality.
