Hi! This is my 1st time in this forum. I have read all about the algae problems from most of you, but I found that no one really concern about the 'Potassium' and I had just overcome the algae problems. When our tank contain too much nutrients, means the algae will growing fast from beyond our control. The 2 ways that I am using now are, add more Potassium into the water & put more Yamato shrimp (but currently I have only 7 Yamato shrimps, still looking for more. Estimated 100litres tank need 40~50 of it to do the jobs.)
I think JBL & Tetra fertilizer has just a little Potassium inside, but the plant really needs more than that for photosynthesis.
