Volcano Posted March 15, 2021 Share Posted March 15, 2021 (edited) Hello! I just found some Seachem in the back of my fridge, which I vaguely remember purchasing from around ten years ago. I couldn't find the expiration date; the liquid is dark brown and smells a bit like soy sauce. Is this salvageable? I thought it was supposed to be clear...Seachem is so expensive...

Mengo Posted March 15, 2021 Share Posted March 15, 2021 (edited) Uh... I wouldn't use it if I were you. I once got a bottle of Seachem flourish from amazon with the seal broken and it was something like what you described but not that dark. I used it for a couple of days and the fish and plants were fine. My new bottle I got expires 2024. So I think 10 years is out of question.

Seattle_Aquarist Posted March 15, 2021 Share Posted March 15, 2021 Hi @Volcano Keep in mind Seachem Flourish is a mixture of chemicals and as such they do not degrade like organics do. Seachem states that the product has a shelf life of four (4) years but that assumes it is kept at room temperature and exposed to light. You have keep the chemical mixture very dark and very cool during this period of time, I suspect it is still viable and will work just fine. It would certainly try it and see, I think you will be pleased. There is nothing in there that will become toxic, worse case it has no effect whatsoever. -Roy 1 1 Link to comment Share on other sites More sharing options...
gardenman Posted March 16, 2021 Share Posted March 16, 2021 Flourish always looks like that in my experience and always has a bit of a smell. I keep mine in the fridge and just give it a good shake before using it. 1 Link to comment Share on other sites More sharing options...
iGoatFish Posted March 16, 2021 Share Posted March 16, 2021 My bottles always start off clearish but when I get the end its black and it still works 1 Link to comment Share on other sites More sharing options...
