Hello all! I have a new saltwater aquarium that has cycled and been running for about a month now. It is a 70 gallon and I currently have a conch, pair of clowns, lawnmower blenny, sailfin tang, and coral beauty in it. I was wondering when I should do my first water change? Also, when should I start rinsing my filter sock out and how often should it be done after the initial rinse? Thank you all in advance!
