Daily Tasks
Keeping your aquarium healthy needs daily care. Small tasks every day help fish stay happy.
Focus on feeding, watching the tank, and checking equipment for the best results.
Feeding Routine
Feed your fish the right amount once or twice a day. Overfeeding can harm water quality.
- Give only what fish can eat in 2-3 minutes
- Use high-quality fish food suitable for your fish
- Remove leftover food to prevent decay
- Feed at the same times each day to keep fish on schedule
Tank Observation
Look closely at your aquarium for signs of stress or illness in fish.
| What to Check | Signs to Watch For |
|---|---|
| Fish Behavior | Hiding, gasping, or unusual swimming |
| Water Clarity | Cloudy or dirty water |
| Plant Health | Yellowing or dying leaves |
| Algae Growth | Excess green or brown patches |
Equipment Check
Check all gear to make sure it works well and keeps the tank safe.
- Confirm filters are running and not clogged
- Check heaters keep the water at the right temperature
- Look at air pumps and bubbles for proper oxygen levels
- Inspect lights to ensure they turn on and off as needed
Weekly Care
Keeping your aquarium healthy needs regular care. Weekly tasks help keep fish and plants safe.
Following a schedule makes maintenance easier and your tank clearer.
Water Testing
Test water weekly to check pH, ammonia, nitrite, and nitrate levels. These affect fish health.
Use a test kit and follow instructions for best results. Record your findings to track changes.
Partial Water Changes
Change 10-20% of the water every week. This removes waste and keeps water fresh.
Use a gravel vacuum to clean the substrate while removing water. Add treated water at the same temperature.
Cleaning Decorations
Clean decorations to remove algae and debris. Use a soft brush or sponge without soap.
Check decorations for damage and remove anything sharp or broken to protect fish.
Glass Wiping
Wipe the inside glass to remove algae build-up. Use a magnetic cleaner or algae scraper.
Clean the outside glass with a soft cloth and water. Avoid chemicals that can harm fish.
Monthly Maintenance
Keeping your aquarium clean is key to healthy fish and plants. Monthly tasks help maintain water quality and tank appearance.
Regular care prevents problems and keeps your aquarium looking good all year.
Filter Cleaning
Filters trap dirt and waste from the water. Cleaning them monthly keeps water clear and safe.
Rinse filter parts in tank water to keep beneficial bacteria alive. Avoid using tap water that may kill helpful microbes.
Gravel Vacuuming
Gravel traps uneaten food and fish waste. Vacuuming removes these to stop harmful buildup.
Use a siphon vacuum to clean the gravel without removing too much water. Clean small sections at a time.
Plant Trimming
Trim dead or overgrown plant leaves to keep plants healthy. This also improves water flow and light access.
Use sharp scissors and cut close to the base or stem. Remove all trimmed leaves from the tank.
Equipment Inspection
Check heaters, lights, and pumps every month. Make sure all equipment works well and safely.
- Look for cracks or leaks
- Test temperature settings
- Clean light covers and bulbs
- Listen for strange pump noises

Seasonal Upkeep
Maintaining your aquarium through the seasons keeps fish healthy and water clean. Seasonal care helps prevent common issues that arise from changing weather.
Follow a regular schedule to manage cleaning, equipment, and fish well-being. Each task supports a balanced environment for your aquatic life.
Deep Cleaning
Deep cleaning removes waste and algae buildup that regular maintenance might miss. It is best done at the start of each season.
- Remove decorations and scrub them gently
- Vacuum the substrate to clear debris
- Clean the glass inside and out for clear viewing
- Change 20-30% of the water with fresh, treated water
Replacing Filter Media
Filter media traps dirt and waste. It loses efficiency over time and needs seasonal replacement.
| Type of Media | Replacement Frequency |
| Mechanical (sponges, floss) | Every 4-6 weeks |
| Chemical (activated carbon) | Every 4 weeks |
| Biological (bio balls, ceramic rings) | Every 3-6 months |
Checking Heater And Lights
Heaters and lights control water temperature and plant growth. Check them every season to avoid malfunctions.
- Test heater to keep water at proper temperature for your fish
- Replace bulbs if lighting is dim or flickering
- Clean any dust or algae from fixtures
- Adjust timer settings for seasonal daylight changes
Reviewing Stocking Levels
Fish grow and reproduce, changing tank population. Check stocking levels each season to keep balance.
| Fish Type | Recommended Space (Gallons) | Max Number per 20 Gallons |
|---|---|---|
| Small Tetras | 1 gallon each | 20 |
| Gouramis | 5 gallons each | 4 |
| Cichlids | 10 gallons each | 2 |
Troubleshooting Tips
Keeping an aquarium clean and healthy takes regular care. Sometimes problems arise that need quick fixes.
These tips will help you identify and solve common aquarium issues. Watch your tank closely to catch problems early.
Algae Control
Algae can grow fast and cover your tank surfaces. It makes the water look dirty and can harm plants and fish.
Reduce algae by lowering light and cleaning surfaces. Avoid overfeeding fish, as leftover food feeds algae.
- Limit tank light to 8-10 hours daily
- Scrape algae from glass and decorations weekly
- Remove excess food and waste promptly
- Use algae-eating fish or snails carefully
Water Clarity Issues
Cloudy or murky water hides fish and plants. It can signal excess waste or bacteria build-up.
Keep water clear by doing regular water changes and cleaning the filter. Test water for ammonia, nitrites, and nitrates.
- Change 10-20% of water weekly
- Rinse filter media in tank water only
- Check water quality with test kits
- Do not overstock or overfeed fish
Fish Health Monitoring
Watch fish daily for signs of sickness. Look for spots, strange swimming, or loss of appetite.
Quarantine new fish before adding them to the tank. Keep water clean and stable to prevent stress.
- Check fish for physical changes or injuries
- Keep water temperature steady
- Feed balanced diets in small amounts
- Remove sick fish to a separate tank
Equipment Malfunctions
Filters, heaters, and lights can stop working. Malfunctions cause poor water quality and stress fish.
Test equipment regularly. Replace or fix broken parts quickly to keep the tank safe.
- Check filter flow and clean if slow
- Use a thermometer to monitor heater
- Inspect lights and replace burnt bulbs
- Have backup power for emergencies
