Florin, CA tap water
Supplied mostly by Cal Am - Parkway, plus 1 other utility. Here's what the water means for your fish.
Disinfectant
Chlorine
Your water is treated with chlorine. It slowly gases off from standing water, and any water conditioner removes it.
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.
From California Water Board lab results (2024).
Nitrate (NO₃)
Up to 17 ppm (Worth knowing)
Typical 10 ppm
Water changes can't take your tank's nitrate below this level.
