Formulated with Malachite Green and Formalin. Use for disease caused by Ichthyophithirius (Ich), Chilodonella, Costia, Oodinium, Trichodina and fungal infections. Microbe-Lift/BSDT is the preeminent broad spectrum malachite green and formalin treatment. It is formulated differently than any other malachite green and formalin mix. Malachite green and formalin are two drugs that are more effective and less toxic in combination than when used individually. This is the definition of synergism. What makes Microbe-Lift/BSDT the preeminent product in this field is the fact that it is formulated with malachite green chloride, instead of the more toxic oxalate salt. As with any malachite green and formalin treatment, do not with other medications. Microbe-Lift/BSDT is the safest and most effective treatment for the control of diseases caused by Ichthyophithirius (Ich), Costia, Trichodina, Chilodonella, Oodinium and fungal infections. Microbe-Lift/BSDT is the ONLY malachite green and formalin treatment that can be used in water temperatures as low as 50-Degree F, thus allowing treatment in early Spring and late Fall.
