Westfield, IN tap water

Supplied by Citizens Water of Westfield, LLC. Here's what its water means for your fish.

Disinfectant

Chloramine

Your water is treated with chloramine. Unlike chlorine, it doesn't gas off when water sits out, and many pitcher and fridge filters aren't rated to remove it. Conditioners that list chloramine on the label break it apart, which frees a little ammonia. Some utilities switch to plain chlorine for a few weeks a year.

Safety for fish and shrimp

Nitrite (NO₂)

Not detected (Low)

Not detected in testing, so any nitrite in your tank comes from the tank itself.

Nitrate (NO₃)

Not detected (Low)

Not detected in testing, so water changes lower your tank's nitrate well.
