Clear water

[Darren]

Hope you keeping well, we have a problem getting clear water, we have a pond 24,000L, a Lotus clear pond 80 set up, just changed bulbs etc last week, plus air pump, I have done the usual treatment for blanket weed, that's all clear, done water test, that's ok, done a treatment for free water clear 2 weeks ago, but still not clear, it does spend most of day in sun is it worth getting another uv light? Or can you suggest something else please

What size pump are you using?

Are these all chemical treatments you're referring to? Not a big fan of chemicals in the pond as all they do is leave you with lots of dead debris. Do you have lots of plant in your pond?

@Darren Is it a natural pond or a lined pond?

 

[Darren]

What size pump are you using?

Hi
The pump is 1,800L ph

@Darren Is it a natural pond or a lined pond?

Hi
Yes chemical treatment, pond is rubber lined

 

[addy1]

I keep mine clear just using plants, lots of them

 

[Lisak1]

Yes chemical treatment,

Chemicals will work to kill things in your pond, but then you're left with a pond full of dead stuff. Including all the micro-organisms that nature provides to help your pond deal with all the dead stuff. Work with nature, not against it and you and your pond will be much happier. Plants, water movement, low organic load - all will work much better in the long run and are sustainable in your pond.

On a 24,000L pond, that pump falls about 20x lower than recommendations. Not saying that would solve your issue, but....

Good catch @EricV !

@Darren - are those numbers correct? 24000L pond with an 1800L pump?

If the UV light doesn't clear up the green in your pond then the light isn't working properly. The water may be going through it too fast or maybe the light isn't powerful enough.

 

[MitchM]

With such low water circulation, there's probably a lot of detritus that has accumulated on the bottom.
Using a pond vacuum and getting the proper size pump will certainly help.

He meant 2x. ideal pump or pumps is to turn the water 1.5x to 2x an hour.

No, I mean it's 20x below the recommendation. Which is, indeed, to turn over the water 1-2x/hour.

re read all thanks.

TO THE OP. you want to over turn the water volume 1.5x to 2x times an hour. aka a 1,000 gallon pond needs a pump to do 1,500 gallon pump and filter an hour to a 2,000 gallon pump n filte per hourr.


your 24,000L pond needs at a minimum 36,000L hr. to 48,000L can be combined
