Water Gardening: What can I do for my pond algae?, 1 by branka

I added a gravel bog filter last fall. I fired it up over a month ago. Within a couple of weeks the pond was clear for the first time in the history of it. It doesn't even have plants in it yet! I anticipate a mild algae bloom with the warmer weather but I can't imagine it being a bad one.

Here's a picture of the bog just after it was completed. It's lined with cobblestones but inside of it is full of river rock, about a foot deep. That will be a good anchor for the plants. It's attached to the pond via a spillway neither of which you can see it this photo. The small bog is a lotus bog.
