So I have a 600litre fish tank, I usually change 1/3rd of the water by removing 1/3rd and replacing it with fresh water. If I was to do it by removing and replacing 10 liters at a time, how many 10 liters would it take to Acheive the same water quality? So if the fresh water was blue dye how many 10 liter changes would get the same shade of blue as if I had replaced 1/3rd(200 litres) in one go?
