Important information for fish owners:

Southern California fish enthusiasts with indoor aquariums or outdoor ponds are being alerted to the increase in chloramines because they are toxic to fish and must be removed before water is used in aquariums or ponds. Chloramines do not harm people or pets other than fish. It is only when water interacts directly with the bloodstream--as in a fish's gill structure--that chloramines must be removed.

Unlike free chlorine, chloramines do not dissipate from water when left uncovered. Two common methods used to remove chloramines are 1) adding specific chemicals or 2) using activated carbon filters. Both are commercially available.

Specialty fish clubs and associations, publications for fish enthusiasts and pet stores can provide additional information and recommend water treatment.
