Step-by-Step Guide:

1. 1. Prepare a Bath: Fill a container with aquarium water, and add hydrogen peroxide at a concentration of 10 ml of 3% Hydrogen Peroxide per gallon.
  2. Add aeration as Hydrogen Peroxide can lower oxygen levels.
  3. Bath Duration: Place the fish in the bath for 5-10 minutes, watching closely for any signs of stress.
  4. Post-Bath Care: After the bath, transfer the fish to a clean quarantine tank with proper aeration.

Best Suited For: External parasites (Ich, Velvet), bacterial infections, and gill disease.

2. Direct Tank Treatment

In severe cases, hydrogen peroxide can be used in the display tank, though at lower concentrations.

Step-by-Step Guide:

1. 1. Preparation: Add 2-3 ml of 3% hydrogen peroxide per 10 gallons of water to the main tank.
  2. Monitor: Ensure increased aeration, as hydrogen peroxide can temporarily lower oxygen levels in the water.
  3. Repeat as Needed: Reapply the treatment every 3-4 days if necessary, but avoid overuse.

Best Suited For: Tank-wide issues like algae blooms or widespread infections.
