I have rinsed the Matrix with water but my tank still turned cloudy after placing them in, will this harm the marine life? Should this be placed on top or below my activated carbon? I used all the 250ml in my 14g tank, will overusing be harmful? I have also brought AquaPharm PUR-II, how does this "REMOVE" ammonia and nitrite? i thought this is a activated carbon the same as AquaPharm BLACKGOLD.
I didn't find the right solution from the internet.
