Recieved my Kit - FIRST RESULTS!

[waterbear]

I don't use metals in my pool - but the purple floaty things is what I get when I test for Calcium - should I have my water tested for metals .

In my experiece 'purple floaties' might be interference from metal or might just be from the magnesium (which is part of the total water hardness). I have found that using 6 drops of reagent 3 first instead of just 2 drops helps to often reduce or eliminate them. The biggest problem with them is they make it difficult to see the blue endpoint of the test unless you look very closely.
It is entirely possible for city water to have metals so that IS a possiblility but if you are using a seqesterant you should not have any problems. If you want to make sure you can have a sample of your fill water tested for metals....Your pool water has seqesterant in it already so metals might not show up on a test. Hope this helps.
