Setting Up Your Siphon
Using a water change siphon helps keep your aquarium clean. Setting it up correctly makes the process easier and safer.
This guide covers preparing your siphon, starting the flow, and safety tips to protect your fish and equipment.

- Submerge the siphon tube fully in the tank to fill it with water.
- Cover the output end with your thumb and lift it above the tank.
- Release your thumb over the bucket to let water flow out.
- Adjust the tube position to maintain a steady flow.
Safety Precautions

Maintaining Water Quality
Good water quality keeps fish safe and plants healthy. Test water often for ammonia, nitrites, and pH levels. Remove debris and clean filters regularly.
| Water Parameter | Safe Range |
| Ammonia | 0 ppm |
| Nitrites | 0 ppm |
| Nitrates | Below 20 ppm |
| pH | 6.5 to 7.5 |
Timing And Frequency
Regular water changes keep the tank clean and safe. The amount and timing depend on tank size and fish load. Smaller tanks need more frequent changes.
- Change 10-20% of water weekly for most tanks
- Check water quality before each change
- Adjust frequency if fish show stress or illness
