Pond Boss Forums INTRO Questions & Observations Seining pictures of my pond I'm draining down

This pond I am planning on renovating has BH in it. Along with the BH's, it too has ramshorn snails. In my other ponds the YP have lots of black spot and that white worm (can't remember it's name).

I am planning on making this 1/4 pond a YP only pond and would love to start fresh. Thanks for the info
