Seachem GarlicGuard is a scientifically formulated appetite and flavor enhancer that has been designed specifically for freshwater and saltwater fish that are finicky around feeding time, such as angelfish and discus. The concentrated garlic supplement greatly increases food palatability as well as containing beneficial Vitamin C, which is a powerful and beneficial anti-oxidant. Completely safe for delicate reef and plated aquariums. Comes in a 100 ml bottle. Directions: Shake well before using. Soak any food in GarlicGuard before feeding. This solution is safe for use with medicated foods (to attract the interest of finicky eaters to the medicated food). For example, to enhance effectiveness against Ich and other harmful parasites use Seachem's Focus and MetroPlex as follows: Add 1 measure of MetroPlex to 1 measure of Focus per tablespoon of food. Completely soak this food mix in GarlicGuard, refrigerate the mixture, and feed once or twice daily for 1-2 weeks.
