Review on 🐠 Convenient Aquatic Solutions: Bnzaq Automatic Fish Tank Feeder - Ensuring Worry-free Feeding during Your Vacation by Edwin White

The timer of this ADF is set when you put batteries in for the first time. The button on the back is for manual feeding. The switch on the back is for feeding every 12 hours or every 24 hours. It dispenses the right amount of food, either dispensing too much or too little food. Remove the transparent food cover and then slide out the food setting door as shown. It slides out by pulling the round handle. After removing the door, you will notice an opening (door) area. Take a small file or sharp knife and make 2 or 3 SMALL cuts in the valve (door) to allow food to pass through (see photo). Slide the door into place. Load some feed and press the manual feed button to see if the correct amount of feed is being dispensed. If it's too small, make the cuts a little bigger. Repeat the process until the desired amount of food has been dispensed. Now I can set the door control to the second or lowest setting and it will deliver the perfect amount of kibble :)
