Time release fish food blocks are an ingenious and inexpensive way to feed fish while you're out of town if you don't have an automatic fish feeder - some last the weekend, a whole week or even up to 2 weeks! Time release fish food blocks contain quality fish foods (sometimes with additional treats); they even clarify your water as they slowly dissolve, releasing fish food at regular intervals. Most require proper water pH, temperature, and circulation to dissolve correctly (all of which you need anyway), so test your water before you leave.

With its adjustable slider, you can set the size of the portion. There’s also a manual release button so you can feed your fish outside the preprogrammed times. The drum is also designed not to stop even if the feed slot is in a downward position. And that's transparent as well, so you know just how much food is left inside. With the integrated fan and ventilation system, the food inside is kept dry.

Most are fully adjustable (you can release as little or as much food as allowed), operate on batteries and will easily attach to the top of the tank.The offers two feeding schedules per day, and is compatible with most fish foods including pellets, flakes, and freeze-dried food. Users are able to adjust the amount of food dispensed in each feeding. The unit includes a manual function setting with memory mode for time-release feeding. This unit is entirely battery powered.
