Does Flourish Comprehensive become ineffective?
 
I have a bottle of flourish comprehensive I have had since about the summer of 2011 when I had my 50 gallon planted. I have kept the bottle in the fridge since I had bought it, remember reading on here sometime back about doing that. Still have about half a bottle left and wondering if it could still be used? Looked on the bottle and did not see any type of shelf life printed on the bottle out label. Thanks :-)

I do not believe it expires. If so it would have a shelf life on the bottle. It's just a mixture of elements and nutrients for plant growth.

That is what I would expect too. But, you can send an email to Seachem on their site, and they are very good at responding within a day (usually). If you do, let us know their response.

It stays "fresh" longer supposedly. I've read this in several articles. I don't have any links as I'm just getting back in the game after a 2 year break.

i hear ya about getting back into the game, ive been that way since i could remember as far as fish go. only ask cause im soon going to need plenty of this stuff on hand. best to keep it in the fridge when not in use also?

I keep mine in the fridge 24/7. The only time I take mine out is when I go to dose my tanks. When I am done dosing I put it right back in the fridge.

On the label Seachem suggest refrigeration. One (or more) of our members have questioned this with Seachem, and been told that it really doesn't matter. I see it now says on their website, "Refrigeration after opening is recommended but not required." This sort of annoys me; there must be a reason why they recommend refrigeration. :roll:

Edit. I do the same as Boredomb, except I keep mine in the wine fridge which is cool but not as cold as the main fridge. I tend to use two 2 liter jugs a year, roughly, so that means they are in the fridge after opening for 6-8 months.

Hmmm... Very helpful Seachem. :-?

I've been wondering this myself lately. . .I've had the same bottle for a bit over a year now, and my plants are still growing, so it still seems to be working well enough. It seems like the kind of thing that you'd want to replace every year, regardless, but there isn't an expiration date, so. . .*shrugs* I've also kept mine in the 'fridge for no other reason than thats what the bottle told me to do, lol. Like Byron said, there must have been a reason for them to have originally recommended it. . .

Anyway, I've sent a message to the company to see what their recommendation is, I'll let you know when I hear back.
