Pool Stains - unsure what kind and best way to proceed

[tmcdonald]

Back to the pool...

Finally got around to ordering and have now received the test kit. I have to admit, it's made me feel stupid, but I think I've mostly got it figured after finally sitting down for a few minutes to read.

One question - my chlorine test says 1 drop =.2ppm, us 25ml sample. for 1 drop = .5 ppm, us 10ml sample.

On the front of the testing box it says 1 drop = .2 or .5ppm chlorine...I'm not sure how big of a sample I need to use here .

Once I get that figured I think I can stumble my way through the rest.

Thanks again for your help,
