Thanks again for the info. I have been reading about this stuff and this recipe seems to be the best to me. Alot of Tropheus keepers say this stuff is great for conditioning them to breed. I have only had my colonies for a short time and they are really young. I am currently trying to switch them over to a couple kinds of Kens flake and NLS. After I get that accomplished then I will start adding this in their diet. When I actually get around to making this stuff I will post back my results.
