Cycling The Tank With Live Rock
Setting up a fish tank with live rock helps start the nitrogen cycle naturally. Live rock contains beneficial bacteria that break down fish waste. This process makes the tank safe for fish.
Cycling the tank means building up good bacteria before adding fish. This step takes time and care but is very important for a healthy tank.
Nitrogen Cycle Basics
The nitrogen cycle turns harmful fish waste into less harmful substances. Ammonia from waste is toxic. Good bacteria convert ammonia to nitrite, which is also toxic. Then another type of bacteria changes nitrite to nitrate, which is safer.
- Ammonia comes from fish waste and uneaten food.
- Good bacteria convert ammonia to nitrite.
- Different bacteria change nitrite to nitrate.
- Nitrate is removed by water changes or plants.
Monitoring Water Chemistry
Testing water helps track the nitrogen cycle progress. You need test kits for ammonia, nitrite, and nitrate. Regular testing ensures the tank is cycling well and safe for fish.
