Water Analysis for Aquariums

Water testing is important to ensure the continued health of your fish. It is essential to familiarise the water quality indicators such as the pH and nitrite levels. Test kits should be considered part of the operating expense associated with keeping an aquarium to avoid fish loss as ammonia and nitrites rapidly rise especially in a newly setup aquarium.
