Aeration of a pond


The best pond is one that copies as best as possible the natural conditions found in nature. You will want to make sure you have an equilibrium and it takes work to create a suitable balance. Just filling up a pond and expecting to be able to leave it to itself just won’t work. Fish in the wild don’t live in the same water every day without having some kind of continuing moving water. Fish and water plants (and other organisms in the water) need oxygen to keep them alive. Always remember that the warmer the water the less oxygen it contains. I learned this the hard way when I only relied on the waterfall to aerate my pond and when the temperatures went up over 80 degrees I didn’t realize until it was too late that my fish were under distress and were hanging out at the top surface of the pond, where wildlife (I think a raccoon) could easily grab 2 of them. I then found out how important it is to have an aerator in the pond and purchased one right away (I also had to purchase new goldfish). I didn’t realize at the time that the plants at night are taking in oxygen from the water and competing with the fish. Its important though to have these plants in the pond to filter and help clean the water. So learn from my example and don’t make the same mistake I did, have an aerator in the pond to keep your fish happy.

Koi or Goldfish in a pond do not necessarily co-exist too well, because the fish love to forage on plants.  Therefore the only solution I’ve found is to keep the number of fish low and the number of plants very high.  I hate to see people stock way too many fish in their ponds.  They don’t realize how stressful it is to the pond environment.  I also think that for wildlife passing by a pond that’s overstocked has to be easy pickings for the poor fish that are already overstressed.  Fish need space to move around (and places to hide from predators), and water plants need a chance to be able to survive.  Some pond owners prefer to screen their plants in the pond away from their fish (a strong plastic mesh fencing for example) on a pond shelving.  You might want to think about shelves while your pond is under construction.

I keep water celery in my pond, along with water lilies, irises.  This year I’m trying to grow water punks (not sure what their technical name is), I loved those as a kid.  Water celery is prolific, which I like since the fish will eat it.  Over the spring the water celery that I had grew up through the rocks and made a nice little field (see picture above) that I didn’t really want so I am going to remove that patch and relocate it to the lake I live near as we need some water plants for there and they won’t cost us anything.  I had planned on doing that this morning but its raining like crazy outside so I guess that will have to wait for another day.

I will talk more about water plants another day, enjoy your week, and share some of your pond experiences with us, I’d love to hear them.
