I have a frag tank ( this being my first saltwater tank). I have some frags that my buddy gave me to get me going. I am feeding with Coral frenzy twice a week. I read other threads that say you can see the corals eating. How do I know if my corals are eating. I know one problem I have that I already know the solution to and thats shutting down the pump so I dont lose my food down into the sump. But I havent had a chance to get a small powerhead to keep things moving while pumps are off. So other then that how do I know if my corals are eating? Any other tips you all could give this newbie would be greatly appreciated. I Know I have a darth maul, a goochster, a gobstopper, and capt. america. There is also an acan not sure what name is, an orange and green lobo, some frogspawn, and a torch coral, and a green favia of some sort. Like I said these where all a given to me from my buddy so I am still learning.
