I am looking for a product called Selcon here: http://www.marinedep...marine-ap.html. I have called Fishy Business, Aquatek, River City, Aquadome, Darby's Tropicals- no one can order it, yet it has tons of great reviews! Does anyone have any of this that I can buy from them or know where I can get this locally, before I have to get it from a mail order supply?
