ChlorGuard™ safely, rapidly and efficiently removes toxic chlorine. Chlorine is commonly used in many municipal water sources to disinfect tap water. Chlorine is toxic to all aquatic life and should be removed before use of such water. ChlorGuard™ should be used whenever doing a water change or adding water. Be aware that many municipalities treat water with chloramines rather than chlorine. ChlorGuard™ will not remove chloramines. Check with your municipality water provider if you are uncertain which is used in your area. If chloramines are used, then use Prime® or Safe™ instead. ChlorGuard™ is an econmical alternative to Prime® when the additional benefits of Prime® are not needed.

Sizes: 50 mL, 100 mL, 250 mL, 500 mL, 2 L, 4 L, 20 L

ChlorGuard™ is the most concentrated dechlorinator on the market. A 250 mL bottle of Chlorguard™ will treat up to 10,000 US gallons of tap water. Our closest competitor’s 8 oz. (250 mL) bottle treats less than 6,000 US gallons.

BEGINNER: Use 2 drops for every 1–4 L (1 qt - 1 gallon*). ADVANCED: 1 drop added to 2 L (2 qt*) will remove 4 mg/L chlorine. Alternatively you may employ the following formula for a variety of chlorine and water levels: (CV)/8=d (for volume in liters) or (CV)/2=d (for volume in gallons*). C=chlorine concentration in mg/L, V=the volume of water being treated and d=the number of drops of ChlorGuard™ to use. For example, to remove 4 mg/L of chlorine in 2 L you would use (4*2)/8=1 drop.
