Selcon?

[MizTanks]

I've order some in hopes of maintaining my lil Mandarins health, along with everything else in my tank. However most recipes call for making large portions. I will be using it only to soak frozen brine shrimp/cyclopees wafer and maybe a few other foods. But in very small daily quantities.

Anyone wanna help me make up a batch? The way I feed now is too thaw out a cube of frozen and target feed. How much Selcon should I add to 1 cube?
