Bubbles forming in my new pond???
Our 5500 gal pond has been running for about a week now. I have added about 10 potted pond plants, 8 hyacinth and a few water lettuce. I have not added fish yet and am expecting some anarchis in the mail soon. This morning I noticed there are now bubbles forming on the surface and under the waterfall. Is this normal, or something I should try to fix before adding fish?
