iOT based aquarium for monitoring and controlling system

Firstly, I need literature review with abstract, introduction and methodology. Im thinking of measuring the water parameters like, pH, temperature and Dissolved oxygen which will be displayed in an LCD and will be transferred to the cloud then to mobile app. Once the parameters reached outside the specific range it will notify the user to perform water change. Water change/drain will be atleast 25% of the total water, and be refilled until the floater stops. I have seen similiar projects but it doesnt have the water change system. Those projects just used for monitoring but there is no controlling part that can improve water quality.
