FritzGuard is a safe and effective pH-buffered water conditioner that neutralizes toxic chlorine, chloramines and heavy metals found in tap water. FritzGuard promotes healing and reduces fish stress with aloe vera and vitamin E and provides 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 and handling.
Use 1 tsp (5 ml) per 10 U.S. gallons (38 L). For best results, add FritzGuard to tap water before adding water to aquarium. For marine aquariums, turn off protein skimmer for 6 hours after adding FritzGuard to reduce foaming if a concern. For areas with very high chlorine levels, dosage can be safely increased or repeated up to 5x.
