I recently bought some chlorine test strips. I wished to verify my tap water contains chlorine and not chloramine which the pet stores always insist. What I found, besides the fact I was right, is the product is very dangerous. I am told that chlorine as low as 0.25 ppm could still kill everything in your tank. At normal 75 F water temperatures these strips state there is no chlorine when in fact there is 0.40 ppm. Almost twice the lethal amount. I have determined through experimentation the problem seems to be 2 fold. The strips only seem to react at temperatures so low they would probably kill most tropical fish. They also only report about half of what is present. I feel that it is necessary to put out this information immediately in case anyone was using aeration or activated carbon for dechlorination of aquarium water and uses this product to test the water for safety.
