New pool new problems -- algae and iron!

Are you still using the K2005 kit to test the chlorine? The chlorine test in that kit is a DPD test and it bleaches out at high levels. So, it can appear that you have no chlorine when in fact you have extremely high chlorine! That is why I suggested that you get the K1515 add on kit so you can use a FAS-DPD test instead which will measure high chlorine levels. Did you get it yet? If not, then you are better off for now using an OTO kit instead of your K2005, along with this chart:> http://pool9.net/oto-chart/

Also, pH tests are invalid when the chlorine is higher than 10ppm with a Taylor kit (and higher than 5 with other kits).
