Thread: Should I change this oxygenator?

I believe the oxygenator in my pond is Ceratophyllum Demersum. See photos. As you can see, the plant tends to grow to the surface and then bunch up which I find an eyesore and the reflections I used to have are now gone. We have a National Garden Scheme garden open to the public so the look of the pond is very important. I'm sure in previous ponds the oxygenator I was using stayed below the water leaving the surface clear. I have tried cutting and reducing the plant with limited effect despite filling 5 wheelbarrows. It also seems to be effecting the growth of water lilies. I'm not sure if the leaves are being stopped from surfacing due to the density of the plant.
Can anyone suggest an oxygenator that is fairly fast growing (the pond is 10 metres long) and will not creat the effect shown in the photo i.e. that will not break the surface? The pond is from 0.6m to 1.4m in depth.

Can anyone advise?

The grass carp 'should' eat the floating and less fibrous stuff and leave the lilies alone. Koi will root around and possibly knock everything about.

You say "surface oxygenators". Do you know of any that are not on the surface i.e. that stay underwater. That is what I need. This is a natural pond with no filtration hence the need for oxygenator.
