Dewman, it is an interesting place to live down here. I live in Brownsville, but also have a house on the beach at South Padre. Most of the summer, we do not have much sargasm at all, however in the spring and early weeks of the summer, we do sometimes get a lot. The floating sargasm actually harbors an unbelievable amount of life. Next time, you are down, you should scoop some up with a bucket while it is still floating and you will find all sorts of neat stuff. Once, I caught 2 sargasm angler fish. Within 1 hr, there was only one (got eaten by its buddy) As far as putting things in reef tanks from here, you have to be very careful (as you already found out) Most of the stuff is pretty nasty and will not be reef friendly. I do a lot of offshore fishing and have caught some very neat things. I am still thinking about putting a baby dorado in my reef tank. I have caught one in the past with a net that was only about 2" long. I am pretty sure that if he survives though, that he will start to eat all the other fish in the tank. Anyway, as I said, I think that adding small amounts of the B-ionic in a large container of water is fine (that is basically what you are doing when adding the stuff to a small tank) I do not see any warnings about adding B-ionic to a tank less than 30 gallons. What probably is true, is that the two parts cannot be directly mixed since something would surely precipitate out at such a high concentration. I appreciate you relaying your experience.
