Love the tank, it looks super similar to my pico reef I keep in my classroom! The sexy shrimp/rfa combo have been some of my favorite animals I've ever kept. Watching them walk around and wave their tails keeps me sane when the students are driving me up the wall. I've been having a hard time keeping my alkalinity above 7 ish though, how are you managing that in a tank this small without causing huge swings every time you dose?
