Wardley Bullseye 7.0 Neutral pH Regulator (4 oz.; pH 7.0)

Wardley's Bullseye 7.0 is an aquarium pH regulator which automatically converts aquarium water to a neutral environment (pH 7.0) favorable to growth, spawning and maintenance of community aquaria. Bullseye 7.0 establishes the pH and then acts as a guardian--continuously making small adjustments in water chemistry to insure a constant aquarium water condition for as long as two months. Stabilizing action of Bullseye 7.0 allows replacement water to be added at any time without affecting pH. Added to freshly drawn tap water, Bullseye 7.0 products pH controlled aquarium water which can be used for complete or partial water changes. One bottle treats 25 gallons.
