- Needs regular cleaning or replacement
- Prevents buildup in other filters
Biological Filtration
Biological filtration uses bacteria to break down harmful chemicals. These bacteria turn ammonia into less toxic substances. This process is essential for fish survival.
Common Biological Filter Media:
- Bio balls
- Ceramic rings
- Sponges with high surface area
Bacteria grow on these surfaces and clean the water continuously.
Chemical Filtration
Chemical filtration removes dissolved impurities using special media. It helps clear odors, discoloration, and toxins. This method supports the other filtration types.
| Media Type | Purpose |
| Activated Carbon | Removes odors and chemicals |
| Zeolite | Absorbs ammonia |
| Phosphate Removers | Controls algae growth |
Water Conditioning Techniques
Healthy water is key for ornamental fish. Proper water conditioning keeps fish safe. It removes harmful chemicals and balances water quality.
Use the right methods to prepare water. This helps fish grow strong and live longer.
Dechlorination
Tap water often has chlorine or chloramine. These chemicals can harm fish. Dechlorination removes them safely before adding water to the tank.
Use a water conditioner or let water sit for 24 hours. This lets chlorine evaporate naturally. Chloramine needs special chemicals to break it down.
Use Of Water Conditioners
Water conditioners make tap water safe for fish. They neutralize chlorine and chloramine. Some also remove heavy metals.
- Choose a conditioner that works with your water type
- Follow the instructions for dosage carefully
- Condition water just before adding it to the tank
- Use conditioners that add minerals for fish health
Beneficial Bacteria Supplements
Beneficial bacteria help break down fish waste. They keep the tank clean and water safe. Adding bacteria supplements speeds up this process.
| Benefit | Description |
| Ammonia Reduction | Bacteria convert toxic ammonia to less harmful substances |
| Nitrite Control | They change nitrites into nitrates, which are safer |
| Tank Stability | Help maintain balanced water chemistry |
| Faster Cycling | Speed up the tank’s natural cleaning process |
Routine Water Maintenance
Keeping water clean is key to healthy ornamental fish. Routine maintenance helps fish stay strong and live longer.
Regular care prevents disease and keeps the tank environment safe for fish and plants.
Regular Water Changes
Change part of the water often to remove waste and toxins. This keeps water fresh and safe for fish.
Replace 10% to 20% of the water every week. Use dechlorinated water to avoid harming fish.
- Remove water using a siphon or bucket
- Refill with clean, treated water
- Avoid changing too much water at once
- Check water temperature before adding
Tank Cleaning Tips
Clean the tank surfaces to stop algae and dirt buildup. Use soft tools to protect fish and plants.
Clean decorations and filter parts regularly. Do not use soap or chemicals that can harm fish.
- Use an algae scraper for glass or acrylic
- Rinse decorations in tank water, not tap water
- Clean filter media gently to keep bacteria alive
- Remove leftover food and debris from the tank bottom
Monitoring Water Parameters
Check water quality often to ensure safe living conditions. Keep parameters in the right range for your fish.
Test for pH, ammonia, nitrite, and nitrate levels. Use test kits designed for aquarium water.
| Parameter | Safe Range | Why It Matters |
|---|---|---|
