Discuss the types and functions of under gravel filters and power filters in aquariums.
Understand the Problem
The question appears to be focused on different types of aquarium filtration systems. It discusses under gravel filters, their benefits, problems, and provides an overview of external and internal power filters, including their characteristics and downsides.
Answer
Undergravel filters focus on biological filtration using the substrate, while power filters provide all three types of filtration (mechanical, chemical, and biological) and are easier to manage.
Undergravel filters provide biological filtration using a substrate and air pump or powerhead; they are more suited for beginners and less expensive but require less maintenance. Power filters offer mechanical, chemical, and biological filtration, are easier to place, and are relatively efficient and inexpensive.
Answer for screen readers
Undergravel filters provide biological filtration using a substrate and air pump or powerhead; they are more suited for beginners and less expensive but require less maintenance. Power filters offer mechanical, chemical, and biological filtration, are easier to place, and are relatively efficient and inexpensive.
More Information
Undergravel filters use the entire substrate as a biological filter, making them highly effective at biofiltration despite their low cost and simplicity. Power filters are versatile, providing comprehensive filtration and can be used in conjunction with other systems like protein skimmers for marine setups.
Tips
A common mistake with undergravel filters is failing to clean them regularly, leading to a buildup of nitrates and potential algae blooms. For power filters, ensuring the media is changed or cleaned regularly will help maintain water quality.
