Measuring Equilibrium

    I have just started using equilibrium (thanks to this forum) in my 38 gallon tank with ro water. The bottle instructions (seachem) says to use 1 tablespoon for every 20 gallons, when setting up aquarium or making water changes. I have been changing 50% water so 20 gallons and using 1 tbsp. Now I am wondering if the instructions mean 1 tbsp for 20 gallons of new water that is added or is it 1 tbsp for 20 gallons of water in total, which would mean I would need to use 2 tbsp. Any suggestions are greatly appreciated.

    It's for just the new water added. You can confirm by checking your Kh and Gh.

    Thanks. I was using the gh and kh strips as they don't sell the liquid test here but I bought it from Amazon so I will have to do some research as I have no idea what a normal number reading is for my fish!
