Reefing newb
i have a 55g saltwater tank and was going to do a slight water change....in doing so, i heard that you can take lets just say 20 gallons out, and add a new 20 in, but my question is is that do you have to add more salt to that water after conditioning it? or can you just add the API aquarium salt to the mix and that does the job just as fine, thats what i have and thats what i thought was right, but just wanted to double check...thanks!!
