Lakeland North, WA tap water
Supplied mostly by Lakehaven Water and Sewer 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)
Up to 4 ppm (Low)
Typical 1.2 ppm
Low, so water changes lower your tank's nitrate well.

Chlorine or chloramine at the tap
0.3–1.7 ppm

At tap levels, chlorine and chloramine are toxic to fish, shrimp and the bacteria in a filter. Water conditioners are made for this range.
