    I just came across this thread. WOW, I didn't realize that 5 drops were that toxic that I should not be throwing it back into 6400 gallons of pool water. Hope I don't accidentally get any drops on my skin. If 5 drops will harm that much pool water, what does it do when thrown directly to the grass if I throw it out in the yard?

    Just be aware that the reagents ARE chemicals and some of them have some hazards.....DPD is an aniline derivative, OTO is dissolved in hydrochloric acid to make the test reagent, TA titrant is usually sulphuric acid, CH buffer is sodium hydroxide. Not really more dangerous than many household chemicals we use every day but they should be treated respectfully and disposed of properly. Dumping them back into the pool just isn't a good idea, even in the small amounts used. Some of them are adsorbed through the skin so if you get them on your hands it is a good idea to rinse them off right away. That is why I do my testing next to a sink. People have a lot of respect for working with muriatic acid. The chemicals in the test kit deserve the same kind of respect even though they won't cause the immediate damage that an acid spiil can cause and we are using them in much smaller amounts.

    Just my 2 cents!
