My water change bucket is 10.5 litres, my water conditioner treats 37.8L of water. So does that mean I should third the amount of capfuls I put it. also my conditioner has 3 instruction parts onr for chlorine, chloramines, and scales and fins. It says to u se one capful for chlorine, one chloramines, and 2 for scales and fins. So should I use just two and that will cover all of it or ?. thanks for any help in advance.
