clogging pump

[CKM]

Hi there, wonder if anyone can help or offer any advice.
My pond is 7x5 built around 20 years ago and has koi of various sizes and colours, and a couple of plants. I have a pump, filter and ultra violet clarifier which feeds through a water feature.
The water is crystal clear, the fish are all eating well and are healthy, I checked the ph levels of the water last week and all is fine. My problem is that the pump is constantly clogging with dark green weed like material. Not 24 hours goes by that I do not have to clear it. I have tried lifting the pump off of the bottom of the pond, but this makes not difference. The material pulls itself into the rotor of the pump and wraps itself around the outer cage, which in turn stops the pump from working.
I'd be grateful for any help or advice. Many thanks

hello and welcome to the forum. Have you tried a universal pump filter box? Big box comes with a couple filter pads and some bio balls, lid pops off and the hose to the pump goes through a hold in the lid and filter pads.

I have my UV filter zip tied to the lid and 2 pumps in it; using rocks to weight it down with ceramic media in bags and carbon in a sock. It's a pain to clean only because of my configuration. It's basically Frankenstein.

How many fish? Average depth of pond? Have you tested for Nitrate?

Pre filter to pump?

algae and probably the one thing that is keeping your fish alive and your water clear .Over feeding the fish feeds the algae also .Pond may also be to small for koi

u need to see why u have alot of algae , may b add other pond plants to share the nuritions , other thing u can do DIY is some thing like mesh box with large surface area that will only increase ur clogging time to a week or 2 but will not be permanent solution .if u install prefilter with foam that will clog even quicker then mesh .

You're already getting good advice, but I'd like to add, that it's not a good idea to have your pump on the bottom of the pond, because if ahose or pipe breaks, it can pump your pond dry.

Thank you, that is a good point that I will bear in mind.

The mesh box idea seems to be a popular idea, so I will give it a try, thank you.

How many fish? Average depth of pond? Have you tested for Nitrate?

Yes the nitrate levels are normal, we have around 15 fish, a couple of them are quite large, the rest are a variety of sizes most have been born in the pond.

Pre filter to pump?

Yes we have a bio filter before the pump.

I am really strict about how much the fish are fed - someone once told me A hungry fish is a healthy fish!

Thanks to everyone who has taken the time to reply.
