Algae growth in aquariums thrives on three basic necessities: water, light and nutrients. Some algae growth is healthy, but over population of algae growth is unsightly and even can lead to hazards to fish and plants that are in the aquarium. With an increase in temperature, the growth of algae also increases. An increase in temperature leads to higher nutrients level in the water, thus allowing the fast growth of algae. In addition, there are fewer microscopic organisms that feed on algae at high temperature, thus all these factors leading to excessive and rapid algae growth in an aquarium.
With the pH levels, temperature of the water in the aquarium, excessive nutrient build-up, and limited number of plants in the aquarium, these are the factors that allow the rapid growth of algae. …show more content…
In this investigation, four aquariums with the same number of algae, same level of pH, and equal level of nutrients will be placed near the window at the same location with same amounts of sunlight at different times of the day. The first aquarium will be filled with half a litre of 35 degree Celsius water, with 1 millilitre of algae plants. The second aquarium will also be filled with the same amount and same type of algae plants, except that the water temperature is decreased by 5 degree Celsius, the third aquarium will then be filled with 25 degree Celsius temperature of water. The fourth aquarium is a control set-up which is filled with average water temperature of 27 degree Celsius. The control set-up allows for comparison of effect of different temperatures of water on the rate of algae
