When a new tropical
fish aquarium is set up care has to be taken to ensure that everything works
well, and overstocking should be avoided, otherwise a new filter may become
overloaded, in which case ammonia and nitrite concentrations can build up, and
poisoning may occur Here are some key points to consider when
creating a new aquarium :
- It takes 21 days for a new tank to become established
- Two beneficial bacteria are important in aquaria,
- Nitrosomonas - convert ammonia to nitrite
- Nitrobacter - convert nitrites to nitrates
- These bacteria can be added to the tank to get it going by :
- Adding some gravel from an established, disease free tank
- Adding a starter preparation - commercially available
- Adding a pinch of garden soil containing the bacteria
- To avoid cloudy water wash new gravel up to12 times with a hose until
the run off water is clean
- Disinfect all rocks before introducing them into the tank using
Potassium permanganate - in 3mg/litre water for 24 hours or 15 mins in
7.5mg/litre, OR a special aquarium disinfectant DO NOT use household
disinfectants.
- Add plants, rocks, set up under-gravel filters etc and switch everything
on for 2-3 days before adding any fish.
- Before adding fish to the tank check the following :
- water temperature (about 24 degrees C)
- pH (should be 7.0)
- ammonia concentration
- nitrite concentration - should be less than 0.5ppm
- Start a new tank with a few healthy, hardy species of fish, such as:
- Barbs
- Catfish
- Danios
- Livebearers
- Loaches
- When introducing new fish into a tank differences in temperature and pH
between the water they are bought in and the water in the tank will
determine how long it will take to introduce them. Tear the plastic bag
the fish have arrived in and float it on top of the tank water and
gradually add tank water into the bag - about every 10 minutes. Take half
an hour if the temperature and pH are similar, but take several hours to
fill the bag with tank water if the temperature and pH differences are
great.
