| Each block feeds aquarium fish for up to 3 days. Perfect for mollies, catfish, algae eaters, snails and similar fish. To use, simply place the block in your aquarium. Within hours, it will start to dissolve, releasing nutritious freeze-dried foods while also neutralizing your aquarium water.
One block will be sufficient for 10 to 15 gallon tanks and will last 3 to 4 days depending on the pH level and water temperature. A minimum temperature of 72 degrees F and pH of 6.6 to 7.0 is recommended. Highly alkaline water will slow down food release.
Proper water circulation through means of an air stone or filter is required for blocks to dissolve normally. 4 food blocks per package.
Ingredients: Calcium sulfate, Freeze-dried daphnia, Shrimp meal, Spirulina, Vitamin B-1, Vitamin B-2, and Vitamin B-6. 1.4 ounces (40 grams) per package.
