Water Preparation And Cycling
Setting up a freshwater fish tank needs careful water preparation. Clean water helps fish stay healthy and happy.
Cycling the tank means growing good bacteria. These bacteria keep the water safe for fish by removing toxins.
Water Conditioning
Tap water has chemicals that harm fish. Use a water conditioner to remove chlorine and chloramine.
Conditioned water protects fish gills and helps beneficial bacteria grow. Always treat new water before adding it.
- Remove chlorine and chloramine
- Neutralize heavy metals
- Make water safe for fish and bacteria
Establishing Beneficial Bacteria
Good bacteria break down fish waste into less harmful substances. This process is called the nitrogen cycle.
Start cycling the tank before adding fish. Add a small amount of fish food or ammonia to feed the bacteria.
- Begin cycling with water and filter running
- Add ammonia or fish food to feed bacteria
- Wait 4 to 6 weeks for bacteria to grow
- Test water to check ammonia and nitrite levels
Monitoring Water Parameters
Check water often to keep fish healthy. Use test kits to measure ammonia, nitrites, nitrates, and pH.
Keep ammonia and nitrites at zero. Nitrate should stay below 40 ppm. Adjust water as needed to keep fish safe.
- Test water weekly during cycling
- Keep ammonia and nitrite at zero
- Keep nitrate below 40 ppm
- Maintain stable pH for your fish species
