I use Cylopeeze reguarly. Once in a while some DT's too when I have some. I do not just spot feed though, I release it as a cloud in their area. I have a lot of other critters that benifit from it too. I like seeing the little guys all close up as the Cyclopeeze floats on to them. Works a bit better if you slow the flow some while feeding too. Like slack tide times in nature, something we seldom do or think about in our tanks.
