about my experience to defeat the algaes :
- stop the fertilization during one week
- water changes every 2 days (10L)
- stop one light (the aquastar in my case)
- cut plants
about the fertilisation :
flourish + flourish iron + flourish excell + flourish potassium + dennerle A1 daily NPK + ECA + Green gain + phyton gin
