I use Prime. Usually when I add it I dose for the whole tank but sometimes I forget and only add enough for the amount of water I take out. How much do you guys normally add when doing water changes?
depends on whether your filling it via a python. the thought being that if you treat the entire tank volume then it should be dispersed well to deal with all the chlorine coming in. howeer with good circulation in the tank thats probably not neededBarbie said:You only need to add enough dechlorinator as you add water to the tank, not the entire volume of the water. The only water with chlorine will be the new water.
