I didn't say do what they said.
LOL!
hee hee...
Point taken!
But, even so, when my pool store supposedly tested my water for metals before, they told me there was no iron, but a lot of copper. Of course, this test was done AFTER they had me put Black Algaetrine in the pool and they didn't seem to make the connection -- even AFTER I reminded them!
<sigh>
If I had time, I'd go to a pool store I trust in a neighboring town, but alas, my children have my schedule completely BOOKED for the next 3 days!
Is there a do-it-yourself metal test kit for pools??

Marie, THANK YOU! THANK YOU! THANK YOU!
That's exactly what I needed to hear!
One question though: When you say,
When you put fill water in, put it in through the filter.
What do you mean? I'm not sure I understand what you are saying... Do you mean put it in through the skimmer? Like put the hose in my skimmer?
I'm sorry if I'm being dense; I was up with the baby half the night.
Thanks again!
