I have never used those products with the exception of selcon which I will use to soak frozen and flake food in before feeding. For the majority of my feeding I use a mash that I make myself which I use a variety of fish and shellfish to which I add flake food, selcon, cyclopeeze and garlic. Works for me. In addition I add Ecosystems reef solution and live DT's. I have recently tried out the Phyto feast live and am quite impressed with that and will be switching as soon as my DT's run out.
Don't know if that helps or if any of these products are similar to the ones you were inquiring about.
FWIW I am going to be going to the zeovit system on my new setup and I know that some of these products have a shelf life that is fairly short.
