Freshwater Fish Tip

Martha Stewart Living Television

Fish are sensitive to changes in their water pH levels, and most freshwater fish thrive when their level is at seven. The pH levels in a tank will naturally fall as time passes and should be checked weekly. Look in your local pet shop or fish supply store for specially formulated drops which will correct lower pH levels. If you change the water or add new water, be sure and check those levels, too.
