Hi,
Today I took a look inside my Blagdon filtration system and found numerous horrible worms/leeches crawling up the side of the vertical wall separating each chamber. I have taken 2 photographs and inserted them below; how do I prevent them from getting within the filtration system and could they potentially harm cold water fish?

Would appreciate any information regarding how compatible these worms/leeches are with fish.
