Internal filters are probably the most widely used aquarium filters - and for good reason. They are very easy to use and provide adequate filtration. They also include an air tubing vent to spray oxygen in the aquarium. Designed to sit inside your aquarium, they are the perfect filter for most popular aquarium sizes housing a variety of tropical fishes. Replaceable cartridges make maintenance simple and convenient.
These handy filters are recommended for any hobbyist requiring reduced water movement inside their aquariums. They are best suited for small aquariums housing tropical schooling fish such as neon or danios. They have the advantage of space saving as they hang up at the back of the aquarium hence allowing even more space for the fish to occupy. The replacement filter cartridges are often sold seperately for ease of maintenance making these filters a very good choice.
Canister filters provide superior mechanical, chemical, and biological filtration for larger aquariums or aquariums with a lot of fish. The body or "canister" portion of the filter is significantly larger than most power filters - imagine how much media canister filters are able to hold! Depending on the model, canister filters will have one to three (or more) large media baskets to hold different filter media types. Each media type is layered on top of each other to maintain excellent water quality. Compared to power filters, canister filters require slightly more effort to set up and maintain. However, you will be amazed by their filtering power. These multipurpose filters are ideal for African and South American Cichlid aquariums, saltwater aquariums, as well as freshwater planted aquariums.
Besides simply powering your filtration system and providing water movement in your aquarium, submersible pumps can also be used to power other devices such as UV sterilization units, to drain or fill your tank, or for water changes. They are easy to install and require very little to zero maintenance.
Air pumps can be used for filtration, oxygenation, and decoration. Although air pumps are installed outside the aquarium, they should be as close to the aquarium as possible for best performance. Other equipment you'll need for optimal performance includes airline tubing, an air control valve, and a check valve if the air pump is sitting below water level. The check valve may prevent water from siphoning back up the air tube which may cause flooding.
Tropical fish can be acclimated to a wide range of water temperatures, but they cannot tolerate constant fluctuations from day to night. A heater is used to regulate temperature from these daily fluctuations. Most heaters available on the market include a safety switch which automatically interrupts power should the heater develop a short; a very important feature vital to all fishkeepers.
Aquarium lighting allows hobbyists to observe aquarium inhabitants. But more importantly, proper aquarium lighting provides vital energy to photosynthetic plants and animals. As the primary light source (and in most cases, the only light source), proper aquarium lighting is essential for any system that contains photosynthetic organisms such as plants. Lighting also influences fish behavior and physiology and is vital for the overall health and well-being of the entire aquarium.
