This project was designed to make the cleaning process of an aquarium easier. Changing the aquarium water can take hours and it is not an easy task.
Two Solenoid Valves are used which work as Make Up and Draining Valves. The draining solenoid valve will energize when the pH level of the water is below the minimum level (5.8pH) or higher than the maximum level (7.8pH). The Turbidity Sensor will perform checks, and if the level is high the Drain Solenoid will energize to initiate the draining process.
Each and every move of this project is controlled by an EEPROM. It takes 23 minutes and 12 seconds to drain the water from a 9167 cm3 aquarium and 24 minutes and 53 seconds to replace the drained water.
The specially designed food-feeder box is made up of a 9 volt motor together with a gear to churn the food. A small hole is made on the box to allow the flow of the food into the aquarium. The automatic food feeder works on a 24-hour basis and also each time the make up process stops.
This project will ensure that the pH and turbidity of the water is well maintained. Besides this, it reduces the time spent maintaining the aquarium. With this design one can safely go on holiday for a few days without needing friends or neighbors to help feed the fish and clean the aquarium water.
|What Aqua Kleen Does
Automatically drains the water
Common Problems Faced by Aquarium Caretakers
Difficulty in changing the aquarium water
An automatic control system to maintain proper living condition for fish in an aquarium. Any aquarium tends to build alkali level and get cloudy when water is not changed at the right time.
A search of books and the Internet was done. An automatic aquarium water changer was found. It works continuously and changes 5 gallons of water every hour. It
does not check for turbidity,
