Well, after taking a hiatus and doing discus for a while, I sold off the discus and we are returning back to saltwater! I have a 75 gallon tank with 30 gallon sump that I typically keep about 15 gallons of water in. Currently filling the tank back up with saltwater. Dry rock and sand and cycling with Dr. Tim's One and Only! Pretty excited to be getting back into this side of the hobby! Here is an image of the tank as of a day ago: I should add that before we did not use a protein skimmer but will be adding one this time around!
