For good tank maintenance, approximately 10-15% of tank volume water should be replaced every two weeks. A good way to do this is by vacuuming gravel and replacing any water removed during this process. Tank water should be tested every couple of weeks, as water chemistry cannot be seen visually. It is important to test for pH, nitrites, nitrates, and carbonate hardness. It's also important to clean the aquarium walls every couple of weeks. Always be sure to count your fish, as fish death can lead to decomposition and increased ammonia and nitrite in the water.

Treatments to keep all your bases covered

Want to know how to condition your tank water? Pet Circle has water conditioners, biological enhancers, and formulas to balance your tank water completely.
