Got a question about water changes. First off I use RO water for my water changes of 30 gallons out of a 125g aquarium. Do I need to like 2 days before I do a water change fill up my old tank that is 30g add my salt and a powerhead and my old heater and allow it to run for a few days before adding it to my 125g? I heard that its not good to just dump it in right away cause the salt has to dissolve. As soon as my tank is done cycling this will be my first water change
