Recommendation for a solar powered fountain & oxgenating methods

[Mojomummy]

We have quite a large pond & the fountain that's in it at them moment sounds like a tap when it's on & use electricity. I'd like a solar one - looking to pay around £30-£40.

Could anyone recommend one ? Also have seen some other gadget that oxgenates, also solar powered.

Does the barley straw method help as well ?

All hints & tips welcome

barley straw is for killing algae in ponds, not for oxygenating. But I have heard it does work well. Do you have oxygenating plants in the pond?

we have something which is curly & green. I don't want to put anything too harsh in as it's quite a natural pond.

spend a bit more than 30-40 we had one and it packed up after a few months. If I got another I'd get one that stores energy rather than only working when the sun is out unless you live somewhere very sunny.
