I use seaweed selects brown and green sheets. I put a few drops of Kents Garlic Extreme on it first and let it absorb it for a few miniutes so it gets squishy. I attach mine to an airstone on a piece of air tubing and my tangs tear that sucker up within miniutes. I have 2 yellow tangs and 1 red sea purple tang in a 92 corner tank. I also feed frozen brine and mysis soaked in garlic extreme every other day.
