Clearlake Riviera, CA tap water
Supplied by Mt. Konocti Mutual Water Company. Here's what its 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.

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