LOL, Albert I always do. With tanks this size I just prefer to stay away from any type of automatic dosing. One slip up and it could be a recipe for disaster. I checked the Mg it was low as well at 1200. Did a dosing and will test again this evening then re-dose in the morning if the levels aren't to my liking. The system is settling in nicely, so I just want to let it grow for a few months before adding any more frags. I'd like to find a unique crocea clam next time around. Im very surprised that the corals are consuming such a high amount of supplements this early, but hey that just means they're growing. Can't hate that!
