Fritzpondguard is a safe and effective pH buffered water conditioner that neutralizes toxic chlorine, chloramines and heavy metals found in tap water. FritzPondGuard promotes healing and reduces fish stress with aloe Vera, 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. FritzPondGuard provides a replacement slime coat to aid fish that have lost theirs or have been injured due to stress, poor water conditions and handling. FritzPondGuard enhances biofiltration by producing a slime coat over the filter media, aiding in the attachment of beneficial bacteria, like those in FritzZyme biological products. 16Oz treats – 1920 gallons / 32oz treats – 3, 840 gallons / 1g treats – 15, 360 gallons / 5g treats – 76, 800 gallons.
