I set up the 75 gallon today, after filling the tank with warm water using my Python water Changer I added a little under a quarter teaspoon of safe, but the water still smelled like chlorine, so I added some more. I added about the same amount again along with two smaller amounts on the other side of the tank. I thought a quarter teaspoon was supposed to treat 300 gallons. Now I hope I didn't add too much safe, but it still smells like chlorine, Shouldn't the chlorine smell go away after adding safe? I always add safe to my other tanks when I do water changes with my Python water changer, and it has always worked. Do you think the water just has to move around some more?
