Does Flourish products expire??
I recently found a sale on Flourish plant packs, they contain 100ml of flourish, excel and iron for only $5 and I ended up buying two packs since it was a good deal.
I think they are pretty old and the products were put on sale as a result of it. the flourish was a dark soy sauce color, the iron was dark orange and the excel was clear.
I was just wandering if flourish products kind of expire after like 1 or 2 years? I know some people buy a huge jug of the stuff because its more cheap that way and use it for a year or two.
so like, does it stop working or become bad for the fish/plants?
I only opened 1 pack so I am debating if I should return the 2nd one or place it in the fridge or something.
