I feed my corals about twice a week with Kent Marine's Micro-Vert for filter feeders. And you might think this is weird, I've never heard of anything else doing it, but I also very finely grind up shrimp pellets and a bit of algae disks and flakes, and add them to the liquid supplement as well. They seem to like it though, so I guess it's good haha.
Also, if you don't have a calcium test kit, make sure you get one soon, and test your calcium levels before adding any calcium supplement to the tank.
Happy reefing!!! :joy:
