Just want to provide an update. I IM'd neptune last night via their facebook site, and they got back to me within 5 minutes. It was 11:30 at night....probably, got lucky, but still was very nice of them to respond. It wasn't a one word answer either and they seemed very willing to discuss over IM.
They didn't have the product, but I checked BRS again and they had it. Either I missed it somehow, or they just got it in. Anyway, I ordered and it should be here mid next week hopefully. In the meantime I think I might follow nano crazed advice and use sodium bicarb from the fridge.
