3 Ways to Make Your Own Underwater Aquarium Filter
Maintaining a healthy and thriving aquatic environment is critical for the well-being of your aquarium’s inhabitants. One of the essential components of a well-functioning aquarium system is an efficient underwater filter. While there are numerous commercial filters available in the market, you may want to try saving some money and exercising your creative abilities by making one yourself! In this article, we will discuss three ways to make an effective underwater aquarium filter.
1. Sponge Filter
Sponge filters are simple, easy-to-make, and highly efficient in maintaining water quality. They function through air-driven filtration, which not only offers biological and mechanical filtration but also provides aeration.
Materials:
– A large sponge
– Small air pump
– Airline tubing
– Plastic tube (PVC or acrylic)
Instructions:
1. Cut your sponge into a cylinder shape with dimensions suitable for your tank.
2. Drill a hole that’s large enough for your plastic tube (roughly 2 inches) through the entirety of the sponge.
3. Insert the plastic tube into the hole and ensure it stands upright.
4. Connect one end of the airline tubing to the air pump and insert the other end into the open end of the plastic tube.
5. Submerge the sponge filter in your aquarium and turn on the pump.
2. DIY Canister Filter
Canister filters offer powerful filtration suitable for larger tanks with various fish, plants, and structures.
Materials:
– PVC pipe (at least 4 inch diameter)
– Two end caps for PVC pipe
– Aquarium filter media (such as ceramic rings, bio balls or sponges)
– Flexible tubing
– Small water pump
– Power drill
Instructions:
1. Measure and cut two pieces from PVC pipe: One should be long enough to hold all filtration media; another should seal off one end of the pipe.
2. Drill holes on the end caps for water intake and outtake.
3. Apply the end caps to the PVC pipe with a watertight seal.
4. Fill PVC pipe with desired filtration media.
5. Attach flexible tubing to the intake and outtake drilled holes.
5. Connect water pump to outtake tube.
6. Place canister filter in a secure position near your aquarium, connect intake hose to water pump, and turn it on.
3. Bottle Filter
A simple bottle filter using air-driven filtration serves as an excellent alternative for smaller tanks.
Materials:
– Empty plastic bottle (soda bottles work well)
– Aquarium sponge or filter floss
– Scissors
– Small air pump
– Airline tubing
Instructions:
1. Cut off the bottom of your plastic bottle to create an open cylinder.
2. Place aquarium sponge or filter floss inside the bottle, filling it out evenly.
3. Make a small hole in the bottle cap to insert airline tubing.
4. Connect one end of airline tubing to the air pump and insert another end into the bottle cap hole.
5. Screw the cap onto the bottle and submerge it in your tank with its opening faced down.
6. Turn on the air pump.
These homemade underwater aquarium filters will help you maintain a healthy aquatic environment for your fish while saving you money on costly equipment. Experimenting with each method allows you to choose what best suits your individual aquarium needs. Regardless of your choice, always monitor and maintain proper water quality for optimal results!
