No copper! I did what you guys told me, and tried a different test kit. I used the Seachem, and it told me none, including none with R.O. water, but it did test positive with there Cu solution they sent with it. Now granted, it's just one more test, but I've had better luck with Seachem than Red Sea. Tonight, I'll test the R.O. I'm using with the Red Sea test kit just to be sure. I read somewhere that the copper pipes could leach copper only if you have soft water. Up here it's like liquid rock. And no medications were every used on the equipment or the tank. So things are looking good. My ultimate stocking plan is 1 tuxedo urchin, a dozen or so red legged hermits, 1 blood shrimp, 4 skunk shrimp, and a buncha turbo snails. Thanks alot to everyone here who helped.
