Filter for Turtle Tank Shopping Tips

Grime builds up quickly in the tank because turtles pass out a good bit of bodily waste daily. Plus, if you add fish and plants to the tank, you will be increasing the filter’s workload.

Your choice of the best filter for turtle tank water will depend heavily on the filtration methods it uses. Here are the three types you’ll come across as you shop around:

  • Biological Filtration. This is perhaps the most important type. It uses bacteria growing on the filter to ensure that toxic ammonia from turtle waste does not accumulate in the tank.
  • Mechanical Filtration. Rids the tank of solid bits and pieces of debris. Take care how you use materials, such as gravel, in your turtle’s tank as they can clog this type of filter.
  • Chemical Filtration. These types of filters use substances like activated carbon and ammonia removers. Though not always needed, they do an extremely good job of keeping the water refreshingly clean.
  • Avoid Undergravel Filters. These filters tend to utilize both biological and mechanical filtration but because of their location they are not ideal for turtle tanks. They clog easily when the turtle burrows in the layer of gravel on the bottom of the tank.
