FP101-2 Under Gravel Filter 29*29CM

Description

The FP101-2 under gravel filter is a filtration system used in aquariums. It typically consists of a plate that sits beneath the gravel substrate, drawing water through the gravel and trapping debris and waste materials. The dimensions of 29*29 cm suggest it is suitable for smaller tanks or for use in combination with additional units for larger setups.

Here are some key points about under gravel filters:

1. Filtration Mechanism: These filters work by pulling water down through the gravel, which acts as a mechanical and biological filter. Beneficial bacteria colonize the gravel, helping to break down harmful ammonia and nitrites into less harmful nitrates.

2. Aeration: The movement of water through the gravel bed helps to aerate the substrate, which can be beneficial for the root systems of live plants.

3. Maintenance: Regular maintenance is required to prevent clogging. This usually involves vacuuming the gravel during water changes to remove accumulated debris.

4. Installation: Under gravel filters are typically installed at the bottom of the tank before adding gravel. They are often connected to an air pump or powerhead to create the necessary water flow.
