Just returned from a 17+ day vacation. Did a 5 gallon water change the night before I left, and setup a camera that I could view the tank from while away. I also adjusted the lights, reduced day time by 3 hours, reduced light intensity by 30%. I'm very happy with the results upon my return. No real surprises, Nitrates are holding at 10, phosphates still zero (I opted not to setup any phosphate dosing while away as I didn't want some run away issue and expect to only need to dose phosphates until things stabilize). PH at 8.2, alk at 6. I've started dosing alk to bring it up by .5 a day until I can bring it back to 8+ alk which is where it likes to hover when I'm doing normal water changes.
Fish are looking healthy, no aggression, and corals have grown.
