Fish Tank


  • Overcrowding can lead to low oxygen levels in the water, excess waste and even, in extreme cases, fatalities.
  • Conditioning the water. Tap water comes with countless properties that need to be balanced in an aquarium to support aquatic life. To condition water properly, use a dechlorinating agent along with a biological aquarium supplement.
  • Maintaining proper pH levels. pH is an indicator of the acidity or alkalinity of your tank water. Buy a pH test kit to check the pH level. Freshwater fish typically thrive when the pH level is between 6.8 and 7.5, depending on the species, as it is the range that will offer a natural environment that helps your fish resist illness. Check regularly for fluctuations and make the necessary changes to recalibrate as a change in pH greater than 0.3 in a 24-hour period can cause a fish to become stressed or susceptible to disease.
  • Stabilizing temperature. Changes in water temperature can also wreak havoc on aquatic life, so never place your aquarium near a window that gets a lot of sun, or next to heating or air vents that can change water temperatures quickly. Tropical freshwater fish require a constant temperature of 72 °F – 82 °F, depending on the species. An aquatic heater will help you maintain the proper temperature.


  • Maintenance should include regular water changes, servicing the filter & testing the aquarium water.
  • Plan to replace 25 percent of the water in your aquarium once a month; 10-15% every two weeks.
