Pro-Balance Vacation Feeder Block 7 Day Crab Shape

Feeder blocks keep fish fed while you’re on vacation.
Feeding instructions: Simply place the feeding block in your aquarium. Within hours, it will start to dissolve, releasing nutritious freeze-dried foods, while also neutralizing your aquarium water. One holiday feeding block will be sufficient for 10-15 gallon aquariums and will last 5-7 days, depending on the pH level and water temperature. A temperature of 72 degrees fahrenheit and pH level of 6.6 to 7.0 will be advantageous for the most efficient release of food particles. Highly alkaline water will slow down their release. Proper water circulation through means of an air stone or filter is required for holiday feeding blocks to dissolve properly. For fresh water only!
