This video is about what parameters I test for and what I feed and what I dose in my 75 gallon reef tank. I consider this video a tank husbandry routine for anyone in the saltwater aquarium hobby. I use the Salifert test kits to test alkalinity, calcium, and magnesium. I use the Nyos test kit to test nitrates. I use the Hanna checker ULR test kit to test for phosphates. I use ESV b-ionic for 2 part dosing and the brs liquid mag to dose magnesium. I'm using Mikes Phyto to dose phytoplankton and Reef Nutrition oyster feast.
