Arbuckle, CA tap water
Supplied mostly by Arbuckle Public Utility District, 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
Nitrate (NO₃)
11–25 ppm (Worth knowing)

Water changes can't take your tank's nitrate below this level.
From California Water Board lab results, measured before treatment (2023–2026).
