Panacur for camallanus worms, hydra and planaria

use fenbendazole in the form of Panacur sheep/horse wormer to safely clear hydra and planaria from shrimp tanks but I don't know how effective it is on internal parasites that are insulated from the water column.

1.5ml / 40 L Panacur 25

Putting this in perspective I think that is a very conservative dose. I dose about 8x this amount (Panacur100 at 8ml/100L) to shrimp tanks for Planaria, about half of this rate (4ml/100l) for Hydra with no negative effects. At 2-3ml/100l Panacur100 I do sometimes get a few surviving planaria.

 

I think its better to go gently and then determine if you need a repeat dose rather than overdose but knowing the high end is good too.
