Sponges are durable and easy to clean. They come in many shapes and sizes. Use sponges in your filter to maintain clean water and a healthy tank environment.
Biological Media Benefits
Biological media helps keep single-species tanks clean. It supports beneficial bacteria that break down waste.
This process improves water quality and keeps fish healthy. Different media types work best in different tanks.
Bio Balls
Bio balls have a large surface area for bacteria to grow. They let water flow easily around them.
These balls are lightweight and easy to clean. They provide good oxygen flow for bacteria health.
Ceramic Rings
Ceramic rings have many tiny holes. These holes offer space for beneficial bacteria to live.
The rings are durable and last a long time. They work well in most filter types.
Lava Rock
Lava rock has a rough texture and many pores. It provides a natural home for helpful bacteria.
This rock helps filter water and reduce toxins. It also adds a natural look to your tank.
Chemical Media Uses
Chemical media help keep water clean in single-species tanks. They remove unwanted chemicals and toxins.
Using the right chemical media improves fish health and water clarity. Different media target different impurities.
Activated Carbon
Activated carbon removes odors, discoloration, and harmful chemicals from the water. It works by trapping molecules in its porous surface.
It is useful for clearing tank water after medication or pollution. Activated carbon should be replaced regularly to keep working well.
Zeolite
Zeolite is a natural mineral that absorbs ammonia. Ammonia is toxic to fish and can build up quickly in tanks.
- Removes ammonia and some heavy metals
- Improves water quality and safety
- Often used in freshwater tanks
- Needs to be replaced after saturation
Phosphate Removers
Phosphate removers reduce phosphate levels that cause algae growth. Controlling phosphates helps keep tanks clean.
| Type | Function | Replacement Frequency |
| Granular Ferric Oxide | Binds phosphates | Every 4-6 weeks |
| Lanthanum Crystals | Prevents algae growth | Every 6-8 weeks |
| Aluminum-Based Media | Reduces phosphate | Every 4-6 weeks |
