When u guys doing a water change, for re-fill , do u guys add back all those water from the tap water and then add water conditional ? or u guys add the conditional on the tap water some where 1st(from a tub or bucket maybe?)

Adding tap water straight to the tank from the hose tube may be conveniece...but...... I prefer condition 1st, what abt u guys?

I always use buckets, so I add my dechlorinator into the bucket, swirl, and then add to the tank.
