in any dosing regiment, either happy chem's or Barr's, you need to replace the dosing mixture according to the water you are changing... if you take out 5 gallons, treat five gallons of water with your mix and so on. make sure you top of your tank with fresh water before you remove WC water to keep your measurements accurate
so with this said i for example test my water before changing and then lets say i have a 30 gallon remove 15 gallons and pre treat my new water prior to adding it to the tank with what i need to replace what i have taken out plus any additions or leaving any out to balance my tank?
