Hi im struggling with the amounts of this to add to my tank.
The tank is 20 litres. It already has some of both added to it as it is a `new` set up. I am doing a 25% water change = adding in 5litres.It has measure ments on the bottles but there for 38 litte tanks and my maths isnt very good! Basically can anyone tell me how many DROPS per litre to add for a normal water change. cheers Helen.
