FritzGuard® is a safe and effective pH-buffered water conditioner that neutralizes toxic chlorine, chloramines, and heavy metals found in tap water. It promotes healing and reduces fish stress with aloe vera and vitamin E while providing necessary electrolytes.
Naturally secreted by mucous glands, the slime coat is a natural defense system that protects fish from disease, aids in osmoregulation, and reduces stress caused by sudden changes in the environment. FritzGuard® provides a replacement slime coat to aid fish that have lost theirs or have been injured due to stress, poor water conditions, or handling. Additionally, FritzGuard® enhances biofiltration by producing a slime coat over the filter media, aiding in the attachment of beneficial bacteria.
Directions & Dosage
Use 5 mL (1 tsp) per 10 U.S. gallons (38 L).
For areas with very high chlorine levels, dosage can be safely increased or repeated up to 5x.
Tips for Best Results:
- Add FritzGuard to tap water in a separate container before adding water to the aquarium.
- For marine aquariums, turn off the protein skimmer for 6 hours after adding FritzGuard to reduce foaming.
- No equipment restrictions necessary.
- No contraindications: FritzGuard can be used with all other Fritz products and medications.
- Easy measuring: The 4 oz, 8 oz, and 16 oz bottle caps are approximately 5 mL in volume.
- Overdosed? Dosage can safely be increased up to five times. Observe livestock for distress and perform small water changes if needed.
- Test water using a chlorine test kit.
