Leeches In Koi Filter System

Whilst cleaning out my filters, I found quite a few leeches. Is it safe to leave them there or should I get rid off them? How did they get in there? -Nigel

You should get rid of the leeches, they can damage your Koi with their mouths when attach to you Koi and live off of them. It is always a good idea to get rid of any parasites that are in your pond as soon as possible. The leeches probably were introduced by a bird or an amphibian. Make sure you use a fish safe chemical to get rid of the leeches.
