I finally got my Taylor K-1730 copper test kit and tested for copper this morning.
You're supposed to mix the chemicals, stand up the square tube on the little color comparitor card, look down the tube and compare the color to the color chart.
Egad, my eyes are so crossed I found that disappointly difficult. I tried looking in different lights and I THINK my copper is 0.3-0.5 ppm, a little high (I already unplugged the ionizer).
Question - why do you have to look DOWN the tube? Can you just compare color from the side like we do for everything else?
Also - does copper really work for algae control? Should I plug in the ionizer every now and then?
If this level is too high, what is the best "metal out" product out there?
Thanks to any advice!
