Can someone please tell me if this blue/grey water is algae (dead or alive), or copper and or iron? Last week when I took my water sample to the pool store it tested positive for copper .57 and iron .76. Since then I have left a couple of pucks in there and shocked (twice the amt with a dichlor shock), and added a polymer algecide. My tc and fc were at least 10 (per the cheap strips) for a couple of days. I haven't been able to vaccum. Filter has ran 24/7. I read a post by jason that stated if it was not milky/white cloudy than it was algae. (something to that affect). Question- does the tfp test kit test for metals? And if so, how do you reccommend ridding of them? I bought a metal sequestering agent today but everything I read on here says to shock, shock, shock. No, I have not bought the tf test kit yet because for some reason in my little brain I am having a reeeeeely hard time paying 70.00 for it, although I keep shoveling out money for stupid chemicals. Any help would be appreciated.
