Available Sizes/Strengths

  • 100 mg 30 count 

Active Ingredients: Doxycycline Hyclate 100 mg

Directions: 

  • Add 1 tablet (100 mg) into your aquarium for every 10 gallons of water to be treated. Dissolve the tablet by placing directly in the tank. This amount will dissolve rapidly and circulate through the water. Treatment in a hospital tank is recommended. Treat the tank every other day for a full 5 days. Repeat a full 5 day treatment after 3 days if necessary. To avoid stress to the fish due to oxygen depletion during treatment use continuous filtration but remove the carbon filter since it will remove by absorption the antibiotic from the water. Repeat in 24 hours. To remove harmless yellow color, change 20% of water and use charcoal filter until clear.

Caution: For aquarium and ornamental fish only. Not for human use. This product should not be given to fish intended for human consumption. Keep out of the reach of children and animals. Keep container tightly closed and in a cool dry place. In case of accidental overdose, contact a health professional immediately.
