I have some bottles of Seachem Flourish that I bought 5-6 years ago when I had my heavily planted 10g aquarium setup. I'm returning to the hobby with a new 20g setup in the coming weeks and want to know if my Seachem Flourish has "expired" or is passed its effectiveness now???

Thanks!

Would probably be best to just pick up a new bottle, there cheap.

I believe so. You can go to Seachem's website and email them a question about it.
