Crystal Clear isn't an algae killer. It coagulates the fine particles into larger "chunks" that are large enough to be filtered out mechanically. The problem is that the particles of algae are too small and they go right through the filter. CC makes them clump together. It wont harm and plants/animals. It's like $2.50/bottle to treat 400 gallons. Once the algae is gone you can dose 1/week until you get everything balanced......I had to for 3 weeks.
NPK= Nitrogen Phostphates and Potassium, the three essential nutrients for the plants also known as macronutrients. These need to be supplemetnted with micronutrients in the form of Flourish or Flourish Excel
PS. I may have the Micro/Macro flip-flopped, I've been away for a while, someone correct me if I'm wrong
