Praziquantel Treatment (Liquid) 250 g / 8.5 oz

Praziquantel is known to be one of the safest most
effective pond fish medications available for treating a vast array of
external and internal parasites. It will not stress pond fish, damage
filtration systems, or negatively affect the balance of your pond. One
of the biggest advantages in large ponds is that water changes are not
necessary and it only takes one treatment.
