what can I do about excess nutrients in a pond?

what can I do about excess nutrients in a pond?

Question from Lin T
561 1
Hi, I am wanting to make a wildlife pond where there has once been a slurry pit. We intend to dig out the remains left (very overgrown reeds and rubbish) and start from again scratch. The problem is that water from a large field drains downhill into this space and the field is regularly fertilised. I expect there will be too much nutrient in the water draining into the new pond. Are there any ways to reduce the nutrients, such as putting in plants which will mop it up? Any ideas please!

    I would be tempted to form 2 ponds one shallow one for the field water to filter into first and then drain into the main pond, with the first pond, I would fill with reeds to form a natural filter system that takes out a lot of the silt and nutrients out the water before it goes into the main pond
    I don't think it's worth the risk trying to do it all once it's in the pond

      Hi Thomas
      Thinks for your reply
      Unfortunately I have only just found this or would have replied sooner. I too thought about reeds, until I read that they only filter out silt and solid stuff, they don’t actually have any effect on the nutrient load. So am back to square one... but thanks for the thought
