FritzGuard® – Tap Water Conditioner, that effectively detoxifies Chlorine, Chloramines, and Heavy Metals,


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. FritzGuard® enhances biofiltration by producing a slime coat over the filter media, aiding in the attachment of beneficial bacteria, like those in FritzZyme® biological products
