No, would be my thought. If you leave the water in an open container for a couple of days (or add an air-stone to it for a couple of hours) and it still registers chlorine? Then it is definitely something else.are these strips really measuring Chlorine
I don't know how the strips work, does it have a list of ingredients or an MSDS sheet? If they go pink? it is probably DPD (N,N diethyl-p-phenylene diamine)I suspect the readings are false.
They are. In fact you can buy the normal strips and save a lot of money. My local MA did a comparison and found no differences.Not that I can see. I suspect that although you pay extra for the Proscan strips, that they are identical to the bog standard strips.
I'm sure you are right. I would expect they are a pretty standard piece of kit. I get wildly differing results depending on wether I use strips, liquid tests etc. I rarely check and this was the first test I had done since last April.They are.
