Aquascape Praziquantel Treatment is used to treat fungus and external protozoan parasites including Ich, Costia, and Trichodinella. Common symptoms of these types of issues include cottony patches or small white spots on the fish. You may also notice fish quickly rubbing or flashing against surfaces of the pond, indicating a potential issue. Many issues can be linked back to poor water quality, temperature fluctuation or the introduction of a sick or stressed fish. Before adding any medication to your pond or holding system, make sure you verify all water parameters and rectify any issues before treatment. One container treats 1,250 gallons of water. Aquascape is passionate about the products we produce, providing unique products, designs, and features that stand above the competition.
