Hi ppl
* * * * * * *Maybe someone is able to answer this question,

when you do a water change and you top up the tank, and put in ( i use king british tap safe and other stuff for stress at water changes) do you top up these dechlorinators for the full amount of the tank or just the percentage that was changed
it confuses me lol lol??

You only need to add enough dechlor for the new water you are putting in. The water in the tank is already dechlored so you don't need to re-dechlor it.
