That *****. If I can think of the other source, I will post. For some odd reason I want to off the top of my head say that hydroponics or plants had some use for it. It was a long time ago that I used it(well over 6 years ago) so I could be wrong.
I also saw it somewhere recently, like in the past 6 months. It could only have been stingray bay or tropicorium. But you may want to call fish doctors Canton just to check around. Also, try preuss.. Never know, one of those stores I could be on to something..
I hope you all can find it, add those reactors were nice..
