Sunil, Theo, sounds good. I think I'll buy a block and put it in as instructed.
I'll let you guys know if I see any measurable difference in the health of the shiners or of trout.
Have you guys ever experienced a die-off of minnows or forage - like my pond is experiencing to some degree - where the predator species remains okay? The white fungal patches on the minnows is fairly prevalent.
