I use the left over water from feeding the fishes and I put in coral frenzy, PE mysis, and ground up shrimp pellets. I let it sit for about 20 minutes, then I turn off all power heads and spot feed lps, and rics. Ohh I forgot to mention this is all done 30 minute after the light are out and fish are asleep. The key is only feeding a tiny bit twice a week and you will have mutiple split within two weeks. Don't take my word, try it. The rule is if the ric is eating then it's ready to split. Trying to over feed will not work , tried that also, lol. Twice a week worked the best with one ric splitting with 3 mouths. Think of getting all them to split that way.
