Common Equipment for a 15 Gallon Fish Tank

Equipment for a 15 Gallon Fish Tank

If you are a beginner, you might be wondering what are the accessories needed to install and use in a 15 gallon aquarium.

Well, there’s a bunch of accessories you should not forget.

Of course, filters are a must, keeping the water clean all year round. How do filters work? First, they get rid of larger waster particles. Second, they convert the nitrites or ammonia into nitrates. Lastly, they get rid of organic pollutants according to the standards.

Apart from filters, the lighting units are the second most necessary accessories you should have.

Both plants and fish need enough light, so artificial lighting systems can play a critical role in making all living organisms in the tank as healthy as possible.

Similar to filters, lighting units come in different types, including incandescent bulbs and LED strip lighting.

If you experience a hard time making a decision, LED lighting is a go-to option because it is full spectrum. This means your fish and plants in the aquarium would receive the most natural light.

If you already have filters and lighting units, don’t forget to purchase a heater. In case your fish are cold-water species, a heating system might not be necessary.

For tropical fish, a heater can make a big difference. You can choose in-line, substrate, or submersible heaters.

Other accessories and equipment include a thermometer, algae magnet, filter media, water conditioner, water test kit, fishnet, bucket, driftwood, gravel, rocks, caves, and more.
