Haha, I thought about you when I was informed of the new product. I haven't used it personally yet (I will be soon), but I'm told it's been in testing for a while at EbiKen Studios and they're showing really good results, especially when used in conjunction with Ei. Think of it as sort of a shrimp targeted bacter 100.
And it should last a very long time. Dosage is 1 spoon full of these smallish granules per 10 gallons per month.
By the way, I also received a sample of EbiKen's upcoming "Pro Line" Black Titanium spring scissors. Wow. Best spring scissors I've ever seen. The new line has redesigned, grippier grips, and much longer blades. The blades are right around twice as long as on most currently available spring scissors. And they're an awesome sort of brushed black. As much as I love the current EbiKen scissors, these new ones are really quite a step up even from those.
