100 % water changes are not neccsesery 10 % every 10 days (10 gallon tank) chlorine remover should be enough why add all the other chemicals .. keep a pail of tap water in the room add the chlorine remover to that and as you change 10 % of the water you will have aged water at room temperature. read his tank temperature because a room is 78 degrees doesn't mean his water is that temperature they can go up to 82 degrees you may need that in order to control the fin rot.
