I’ve found AquariumSmiths Dewormer and No-Planaria far more effective than other products I’ve tried – and I’ve tried almost all. A single treatment sorted out my snowball shrimp breeding tank. Other products make big claims but require multiple doses and don’t eradicate the infestation. (Be sure to follow the dosage instructions for shrimp and remove your ornamental snails.) Local is definitely lekker! Thanks Prof. Andreas.
