The question of what is the best filter for an aquarium regularly comes up, but it really comes down to why a person needs the filter. Do they have a tight budget and need a basic filter? Are they filtering a large show piece tank? Do their fish have any special requirements?
But if a person is just looking for an affordable, high quality filter for a community tank, then there is no better choice than an HOB (hang on back) filter. These filters come in a variety of sizes and prices, and most are extremely durable.
