Emergency!

No idea... I guess my question is: how did the hair algae get in there in the first place? What did I do wrong or what parameters was I not mindful of enough that caused the algae in the first place? My nitrate/nitrite readings were always low so I'm completely at a loss...
 
Algae spores are always present in water and plants. When you added plants and iron did you increase or added lights?? When the plants was added the spores probably came in at the same time. Algae got foothold before plants did. Once plants get established algae will go away. Personally I would have boiled wood and rocks (not clhorine dip them) and bleach plants.
You did nothing wrong just algae started before plants. If you have enough plants and they get established ==no more problems. GOOD LUCK
 
Bad news, lost another fish this morning--chinese algae eater. Have extremely cloudy water. Really at a loss here...
 
Cloudy water?? is it white, dusty, green?? Did the chlorine bath wip out you BIO?? Check again for ammonia, nitrate, nitrite. First two should be zero and nitrate low.
