Pond filter

[DOD]

Hi all,
I need to replace my Pond filter which stopped working this morning . Need suggestions for the best one to buy.
i have a concrete pond with 3 Koi and 12 gold fish, it’s approx 3000ltrs with the fish, I also have a pond pump with a fountain.

Any suggestions most appreciated.

Can you describe your filter and what you mean by it stopped working? Did the flow of water stop? Where is the actual pump? Is it contained inside the filter? A lot of filters have a separate pump that pumps the pond water out of the pond through a hose, then through the filter. So, has your filter actually gone bad or is it the pump? Either way, most pumps are repairable. Sometimes something gets caught up in the pump's impeller, so maybe the pump is just clogged.
More information needed.
