More knowledgable people than I will have to give you specifics, but I suggest you add no more chemicals (other than to maintain enough chlorine for sanitation and to keep your ph in range) to your pool until you determine the problem (which probably can be done with help from Pool Doc or Chem Geek)... If your issue is metals (iron or copper), high chlorine will exascerbate the issue; if it's algae, your chlorine might be too low (depends on your cya level). Don't use any more of that algaecide... It contains copper. If copper is your problem, you are making it worse. If copper is not your problem, then you are potentially creating a new problem. I can also tell you that it will be difficult to troubleshoot your problem without a test kit... Taylor k2006 or k2006c (which simply has 2oz bottles of the same reagents).
