Formulated with Malachite Green & Formalin. Use for disease caused by Ichthyophithirius (Ich), Chilodonella, Costia, Oodinium, Trichodina and fungal infections.

Microbe-Lift BSDT is the #1 treatment when you do not know what is bugging your fish, a preeminent broad spectrum malachite green and formalin treatment. The only malachite green and formalin treatment that can be used in water temperatures as low as 50°F, thus allowing treatment in early Spring and late Fall. 

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 use with other medications. Not to be used with salt over 0.15% salinity; at 0.15% salinity, monitor carefully and provide high aeration.

Microbe-Lift Broad Spectrum Disease Dosage
Pond Size (gallons) Dosage
Any Add 3.5 oz. per 1,000 gallons of water
Prior to initial use and each of the 3 applications, at least a 20% water change should be made. A nearly total water change (>90%) will greatly improve effectiveness. Carbon Filtration must be removed and UV's turned off during treatment. You do not have to bypass your bio-filter. Do not overdose.
Treat once a day for 3 consecutive days. You do not need to do a water change after you finish the third treatment. After treatment, it is recommended to start using Microbe-Lift Sabbactisun and Parazoryne - this is a 10 day treatment to expel any parasites, bacteria, fungal, etc. and assists healing.

How often: One dose every other day. If symptoms persist after three doses, perform a 25% water change and repeat treatment.
