FAQs

What are the different types of fish tank filters?

Here are a few of the most common types of filters:

  • Canister Filters: An external filter that uses hoses to cycle your water through a canister. This type of filter can meet the demanding needs of large tanks with lots of fish and plants.
  • Power Filters: Another external aquarium filter option, this system utilizes a pump to draw water into the filtration process. Because they’re easy to install and maintain, they’re a good choice for small or medium tanks.
  • Under-Gravel Filters: This fish tank filter is placed under your substrate, utilizing it as one of several filter mediums. It’s best for tanks with a pretty light bioload.

How do I determine the right filter size for my aquarium?

Calculating the ideal size of a fish tank water filter for your tank is crucial to ensuring a healthy environment for fish and plants. You’ll need to balance the amount of water in your tank with the fish stock and filter efficiency to determine the appropriate filter for your aquarium. Two tanks of the same size may have completely different filter sizes, depending on the number of fish and the filter efficiency.

Which types of filters work best for different tank setups?

Here are the best fish tank filter options for a few of the most popular tank setups:

  • Small/Medium Tanks with Low Fish Stock: Hang-on-Back Filter
  • Bigger Tanks with Live Plants: Canister Filters
  • Tanks with Shrimp & Betta Fish: Sponge Filters
  • Beginner Setups: Internal Power Filters

How often should I clean or replace filter media?

A strict schedule doesn’t always dictate when to clean and replace your fish tank filter media. You’ll need to conduct regular maintenance on your filter, depending on the aquarium's conditions, to ensure optimal performance. However, these guidelines may help you stay on track:

  • Carbon Filters: Monthly
  • Mechanical Sponges: 2-3 Months
  • Bio Filters: 8 Months - 1 Year
