Water Quality Dangers
Drs. Foster & Smith Educational Staff

Maintaining good water quality through regular water changes is the single most important action you can take to ensure successful fish keeping.

A monthly change, of no more than 30% of the same temperature water, is recommended. If you've fallen behind on monthly water changes, up to a 25% water change can be done per week until ideal water test results are achieved.
Dip Test Strips provide accurate water testing with the dip of a strip.
Drs. Foster and Smith Instant Ammonia Remover removes ammonia, chlorine, and chloramines, while detoxifying heavy metals.
Poly Filters can adsorb heavy metals and chemicals when placed in your aquarium filter.
  However, don't take the quality of your tap water for granted. Just because you are able to safely drink the water, does not mean it is suitable for aquarium use. The water can look crystal clear and smell perfectly clean, but it may contain substances which are toxic to your fish.

Contact your local water department to request a water analysis. Though daily results vary, it will help you decide what water conditioner is best for your aquarium.

Tap Water May Contain:
Chlorine: Burns fish gills and kills beneficial bacteria that provide biological filtration.

Chloramine: Chemical compound of chlorine and ammonia, both very harmful to fish.

Heavy Metals: Copper, lead, or mercury are toxic to fish and invertebrates.

Herbicides or Pesticides: Both can stress fish, causing illness or death.
