Did my first 1 gallon water change. 10% of 7.5 gallons is almost 1 gallon. 7.5 gallons is the ammount of water thats in the tank give or take. So i took out 16 cups and replaced it with the saltwater I got from the LFS.

SG droped to about 1.023 the next day. So ive been topping off with saltwater over the last few days and now its back at 1.025.

Sorry did not get any pics of this.
