CONTROLLING AND MONITORING WATER QUALITY IN SALTWATER AQUARIUM

Abstract

An aquarium water quality is very important to the fish because its influence their health. To maintain good water quality in a saltwater aquarium, several parameters that have significant impact to the water quality need to monitor and control such as dissolve oxygen (DO) and turbidity. In this study, various water quality parameters are monitor and control include pH value, temperature (°C), DO, level of water, salinity and turbidity. Maintain optimum value of water quality parameters is mean for the health of the fish. Clean water avoids the fish from stress or attack by diseases. In this study, a saltwater aquarium is developed by using Arduino Mega 2560. The IDE software which is Arduino software is used to make the system develop could monitor and control automatically the saltwater quality in an aquarium. Several sensors were installed to the system such as pH, water level, total dissolve solid (TDS), temperature and turbidity sensor to obtain good test result. The system also was include with auto feeding function for the purpose to feed the fish. The test conducted show that the system developed successfully could maintain optimum saltwater quality parameters in an aquarium. The result analysis findings show that the salinity parameter have directional proportional relationship with temperature and DO parameter.
