“The tee works perfectly. I have it connected vertically and no air pockets. After 3 days I saw no copper in my pool using your test strips. When I got the results of a water test from Leslie's Pool, It showed .3 in copper. I mentioned this to the manager who tested my water, and she said in the past when they used test strips no one was showing copper in their water. Now, with their new high tech testing system, many of their customers who never had copper are showing levels of copper. I am still trying the test strips but they still show nothing.”
