Maintaining a Healthy Fish Tank
While fish-keeping is an addictive hobby; as with all pets, a healthy fish tank and caring for your fish requires commitment, a little bit of science, and regular cleaning.
Your fish need properly balanced water to remain healthy. This means their water needs to have a stable pH and be free of the harmful toxins (ammonia, nitrite and nitrate) which their waste creates.
- Regular cleaning and the correct filtration system will help to retain this balance
- Clean the gravel weekly using a gravel vacuum
- Remove algae from glass or ornaments using an algae scraper
- Carry out a simple pH test once a week
- Change 20% of the water in your tropical or coldwater tank, or 10% of the saltwater in your marine tank, each week
- Only use water from your tank to wash filter sponge, never tap water
- Never use detergent to clean your tank or ornaments
Introducing New Fish
- Toxin levels will change when new fish or plants are added so only add a few new fish at a time; to allow the tank’s bio load to adjust
- Test toxin levels before and after introducing new fish
- Always follow correct acclimatisation procedures
